the gba was a very populur handheld for its days with verry popular series like mario pokemon sonic zelda metroid final fantasy and ETC.
but what about all the other gba games we loved but people just dont know what it is.

AstroBoy omega factor, drill dozer, gunstar super heroes

robopon 2,riveria,bokai,tales of phantasia,

Omega Factor and Drill Dozer are seriously 2 of the best games on the GBA. Omega Factor is an especially criminally underrated game. I mean, it's based off of one of the most popular anime based off of the grandfather of manga's best known work and is a gigantic love letter to all of his works. While simultaneously being a brilliant beat-em-up/shoot-em-up hybrid game. with a really good story with some of the most clever use of replayability in any game ever. I think it came out in 2003, which makes it as good as the brilliant first Warioware game and almost as good as Wind Waker in terms of games that year. And honestly if the music was as good as the rest of the game, I might have liked it as much as Wind Waker (granted, random comparison is random). Seriously, anyone reading this that cares about cool action games or manga needs to play this game. It is awesome.

now to turn around and make every niche gamer angry. Did not like Gunstar Super Heroes that much. Dunno why beyond not liking the music, it just never did anything for me. Granted, I never replayed the game like you're supposed to.

That one frogger game, and namco museum.

If you're referring to Frogger's Adventures: Temple of the Frog, then holy moley I played that game to death as a kid.

I never hear people talk about DK King of Swing that much, which is a shame because that game is spectacular.

Wow! mad props to both KK and Hokori! You took the words right out of my mouth! Just a couple of days ago, I started playing Klonoa:Empire of Dreams. This game is a MUST-PLAY for any fan of Drill Dozer or Astro Boy! I absolutely love it and now begin the hunt for Klonoa 2! Also, I really liked Monster House for GBA. It plays like A Link to The Past, but more puzzle-heavy. It's a really nice surprise for a licensed title!

I feel ashamed to say I've barly played any GBA game (except the ambassadors, Pokemon Ruby, LG, Emerald, and DK King of swing) but I'll get Drill Dozer, and AstroBoy if they come to VC (although I don't see any likelyhood of AstroBoy coming at all.... Saddle )

Ninja Five-O is one of the real gems in the GBA library despite being extremely expensive and hard to find. But it is an excellent game.

I have Klonoa 2 aka Dream Champ Tournament (I think that's what it's called). Very, very good little game, though I prefer the Wii game.

I can vouch for every single game mentioned here so far. Great job, guys. Except Tales of Phantasia. GBA version had too much slowdown, otherwise it would be a great game.

Not mentioned:

Breath of Fire - The GBA version features a Run button, which I don't remember being in the original game. Otherwise this is an underrated game in general. It's brisk, simple, yet creative, and a lot of fun for an early SNES RPG. It's also surprisingly not that difficult, so long as you keep your wits about you.

Summon Night: Swordcraft Story - While it's graphics were dated when it was released, it had a surprisingly pleasant story with likable characters, and a combat system that really worked right and rewarded variety and skill. Its also oft-forgotten sequel, Summon Night: Swordcraft Story 2, is even better in every regard, featuring a much more rewarding crafting system and more varied dungeons to explore.

Boktai 2: Solar Boy Django - An even better game than the original, featuring more varied combat, while still including the stealth gameplay that made the original so fun.

Super Robot Taisen: Original Generation - Great SRPG (especially if you're a mecha fan), I dare say it's one of the best. Engrossing story, likable characters, and awesome robots. I also liked the strategy and it was one of the first SRPG games I ever got a handle on. The second part, also oft-forgotten Super Robot Taisen: Original Generation 2 features improved animations during battles and a continued story. Unfortunately, it also features a racked up difficulty. Luckily there's an anime version for those who couldn't get all the way through it.

Zone of the Enders: The Fist of Mars - The underrated Mecha series had an SRPG on the GBA? Who knew. it's quite good, too. Takes a lot from Super Robot Taisen, but also throws in some new action-y elements, too, which can be turned off if you don't like them for some reason. The story is also good, better than ZOE1 at least, and I liked the characters quite a bit. The stages and situations were also quite varied.

Tactics Ogre: The Knight of Lodis - Best SRPG on the GBA, bar none! Great 3D gameplay, great story (with skippable cutscenes), and some great 3-dimensional gameplay that was challenging without making my head explode. Oh, and it let you recruit your enemies as allies through negotiation. How cool is that? Lost 3 guys? Go get some more...from your enemies side! Not that it's easy, it's actually quite a risk, but still, I love it. Too bad you can't recruit the enemy leaders, though.

The King of Fighters EX 2 - Best fighting game on the GBA. Plays smoothly, just as KOF should.

Iridion II - The best shooter on the GBA, though that's not saying much. It's certainly quite fun, and looks great, too. Predecessor to Nanostray.

And that's all I got that hasn't been mentioned (#9 is the highest I see right now). Would be interesting to see what more people list.

summon knight swordcraft story 1 & 2 was so awsome i love those games and i always will love boktai 2
