Most solid fighting game for the GBA! As someone who has spent a lot of time playing fighting games, I can say that Super Street Fighter II Turbo Revival is one of the best fighting games available for the Game Boy Advance. The game offers a wide range of characters to choose from, including all the classics from the Street Fighter franchise, such as Ryu, Ken, Chun-Li, and Guile. Each character has their own unique moveset and style, providing a lot of variety!
The game also plays very smoothly and responsively. It's impressive how the developers managed to translate the fighting mechanisms of the Street Fighter series to the Game Boy Advance. Everything feels intuitive; it's easy to perform combos and special moves, and blocking and dodging attacks work wonderfully.
When comparing Turbo Revival to other fighting games for the Game Boy Advance, I believe Super Street Fighter II Turbo Revival is one of the best. The other fighting games for the Game Boy Advance, such as Tekken Advance and Mortal Kombat: Deadly Alliance, don't have the same depth. This game is much more focused on technique and timing rather than button-bashing.
