We all know the GBA as a sort of “snes plus” in a way, but it was much more 3D capable than given credit for, largely due to the incredible efforts of a few teams out there. I'm gonna share a few of them!
Stuntman:
How can you go wrong with that amazing facial capture!!! The proper game is pretty slow, and uses a kind of otherworldly-feeling texture style with sprites for cars. But it works!
Asterix and Obelix XXL
A 3D platformer on the GBA! The character sprites have so much squash and stretch to them that you almost forget they're 2D. Looks nicer on an actual screen, but there's loads of texture warp of course.
Need for Speed Underground
Not only is it full 3D, it has official licensed music! You can see all the visual glitches and hear the audio pops but it's still quite a feat. I never would've cared to play this at the time, just feels like a mediocre port of a game I wasn't that interested in. But as a GBA curiosity it's quite something.
Star-X
Star Fox-like! I never played it, but it looks smooth, and sounds familiar.
V Rally 3
Notable because, as I saw in a video another guy was doing about this, the cockpit mode covers up the texture warp, which is CLEVER. Also interesting that most of these are racing games, I guess it was easiest if you could lock the perspective there.
Smashing Drive
the famed(?) spanish arcade game comes to the GBA for some reason! pretty cool. Runs real slow, but as a friend says looks like car-based Bulk Slash almost.
Any more favorites out there? The GBA really struggles with this stuff, and none of these games are amazing, but to look at them in 2020 with a bit more knowledge, it all feels quite impressive.
