Yeah, I'm probably going to do one of these for every platform I own.

Bust a Groove - This one had the unfortunate timing of being released before rhythm games really caught on.A pity, as they not only have some catchy tunes, it's got a unique twist on the gameplay as well.The twist is that it's also something of a fighting game - as you pull off comboes a power gauge builds up, and once it's full you can literally attack your opponent to disrupt their combo streaks.Of course, they can dodge if they tap the button at just the right moment and continue their streak unabated, so it requires you to not only keep in time with the music, but to keep an eye on any attacks your opponent attempts.Definitely creative, if nothing else.

Mega Man Legends - No, it's not really a Mega Man game.Yes, it's still fun.It's something of a Legend of Zelda styled game mixed with a few elements of the Mega Man series.Search around, complete sidequests, find hidden items, and tackle dungeons with big tough bosses at the end.It had a couple flaws, most notably a couple of dopey control issues; first is the fact that you must use the L1 and R1 buttons to turn left and right under the default control setup; fortunately this is fixable.Secondly, your character can circle-strafe and fire, but if they use the lock on feature to aim at an enemy, their feet are planted in place until the lock-on is released, which pretty much defeats the purpose.Fortunately your shots are semi-homing, which eliminates the need for a lock-on in most circumstances.All in all, a fun game in spite of its few flaws and overly short length.

Monster Rancher 2 - Tecmo's counter to the ever-popular Pokemon, with less emphasis on RPG-styled exploration and more on training your monsters for tournament-styled battles and fighting your way to the top.Monsters can be generated in a number of ways; you can snag some for free in the marketplace, though these are limited to a few common types like Mocchis and Arrowheads.New monsters can be created by fusing together two old monsters, usually carrying over some traits from their "parents".But most impressively, you can generate monsters off of any CD for use in the game.And given the fact that there are over 400 possible variations in the game, this feature alone adds considerable replay value.As for the training aspect, it's an elaborate balancing game; training not only costs money, but increases fatigue and stress, which decrease your monsters' overall lifespan, and if they become too much of either they can become sick or run away, which will cause them to lose 2-3 months of potential training time (and shorten their lifespan even further).Oh, and battles, while they serve as your primary source of income, will also lessen your monsters' lifespan.So much of the challenge is not in making your monsters strong enough, but making sure that they last long enough to make it all the way to the top.

It's a strangely addictive formula; unfortunately the series seems to have hit its peak with this game.Ah well, I'll still give Monster Rancher DS a try, if for no other reason than the fact it'll probably require you to buy some crappy Barbie GBA game in order to generate the most powerful monster available.

Omega Boost - I think this was the last game Polyphony made before they began concentrating full-time on the Gran Turismo series.Just a shame it didn't catch on, as it's practically the 3D equivalent of the Dreamcast classic Bangai-o; Lock onto enemies, fire volleys of lasers and homing missiles and dodge out of the way of their counterattacks to some metal tunes.The only downside is that it's short - only nine stages long.Still, it's fun to just start it up once in a while and blast away tons of enemies to rack up points.

SaGa Frontier - Square's lesser known RPG series is SaGa, which sells on its more open-ended gameplay and storylines (making them more like the Ultima or Might and Magic series than other, generally linear console role-playing games).While I've made no secret of the fact that I think Unlimited SaGa is one of the worst games ever made, I do like the few others I've played.My favorite, though, would have to be this one.Set in a strange modern world with some definite fantasy influences (most notably the airships, friendly monsters and robots milling about the populace, and, of course, magic), the game actually features seven smaller quests in one.In one sentence apiece, they are:

Red - A man fighting crime as an unwilling superhero.
Blue - A magician on a quest to master every type of magic, which entails killing his twin brother.
Asellus - A woman who finds herself transformed into a Mystic by the vampire-esque Lord Orlouge.
Emelia - A woman seeking revenge for the murder of her fiancee, a crime she was framed for.
Lute - A kid just roaming around in search of adventure.(Yeah, this quest kind of sucks.)
Riki - A monster seeking seven magic rings in order to save his home world from destruction.
T260 - A robot with a vital mission to complete, though first he must rediscover what it is.

While none of the seven quests is very long, they're all pretty fun to play, especially since you're very rarely bound to a linear path; more often than not you can just break off from the main quest any time you choose and just explore around for a while or partake of one of the game's many sidequests.It's strangely entertaining.

Silhouette Mirage - Apparently adding challenge to a game is a grave sin these days, as many Japanese purists condemn Working Designs' revamp of this title for being too much of a money-gathering game.Never mind that these same people turn around and gold-mine in World of Borecraft for hours on end, heh.At any rate, their claims are greatly exaggerated; you only need to gold-build a few times anyway to grab the game's best weapons, and once you do that it becomes a pretty fun side-scroller shooter in the vein of Mega Man or Contra.And since the game's relatively tame compared to some of Treasure's other ball-bustingly tough titles like Sin & Punishment and Astro Boy, I'll go ahead and hammer them for slamming on the added difficulty of the US release as well.So yeah, take that.

Tecmo's Deception - An obscure trilogy of action titles with a common premise - eliminate your castle's invaders by setting up traps and leading them in. The later games would also emphasize upgrading and combining traps (combining lighting and arrow traps results in a laser, for example) and creating Rube Goldberg-esque comboes to destroy your enemies more efficiently. While the storylines and your protagonists' motives vary from game to game, they all remain enjoyable, dark storylines. Those who are offended by story elements like deals with Satan and violent revenge on entire villages probably shouldn't play them, though.

UPDATE: There's actually a fourth one on the Playstation 2, though they ditched the Deception title and called it "Trapt" for some dopey reason. Regardless, if you liked the first three, check it out.
