I really wish the Analog Pocket plus all the things I want to get for it (dock, all the cart adapters) cost less than $400 🥵 But you pay for quality I reckon! I’ve been stocking up on lynx and game gear carts in anticipation, because I’ve got enough functional GBAs.
As for GBA software, some folks are already doing the good insert credit work for me and already mentioned a lot of the exact games I would have (summon night swordcraft story, riviera, drill dozer).
Here’s some more hot ones which may or may not count as obscure, but nevertheless I think are underappreciated (or underplayed due to expensiveness):
Ninja 5-0 - just a pure action game with amazing movement and snappy feeling that really has a rhythm and flow to it. It feels like it was designed for precision play and speed running. You just can’t beat it for action movement. Also, so much GBA music sounds bad to me now, and the synth sounds in this one hold up.
Darius R - sort of a “remix” of darius but all the stages after stage 1 are exclusive to this title.
KOF EX2 - gets a bad rap, I think, and is a pretty decent game. You’ll have more fun playing it on an analog pocket too, with the four face buttons.
Kururin paradise - got to love that irritating stick! Also, it’s by Eighting.
Racing Gears - if you like euro style top down rally arcade games, this is a good one.
Onimusha Tactics - a simple but very well done tactics RPG that I continue to sing the praises of for ever. distinctive sprites and unique poses help differentiate all the characters for me, even though they’re often bunched up.
Dragon Ball Advanced Adventure - combo-based action side-scroller with a huge number of moves and special attacks, which makes for a more varied experience than most dragon ball games. I would say this is “the good one” on GBA, since there are so many DB/Z games on here. Main downside for me is it’s quite long.
That’s what I got!!
Honorable mention to the Catwoman game which has really interesting movement? I recommend everybody give it a try, even if the game itself is rather pedestrian. it feels really good to scale buildings and jump around things, surprisingly so!!
