I havent played any other gba boxing gams so i cant make any comparisons. But this game is a fun pick up and play boxing game. I never play it for more than like 20 mins at a time. But its pretty fun for a short amount of time every once in awhile.
Its from the first person perspective so u just see ur boxing gloves floating around and the other person. You can block high or low. So the main strategy is to try to punch the person in the area where they are not blocking. Each character has different speeds and combos , and learning combos is important to being good.
The game has a mode where u fight for a title belt. you fight a bunch of people until u get to the championship round. There are a few different difficulty modes.
Also this game has a survival mode which is what I usually play. Opponents are weaker than in the other mode and once you knock them down once they are knocked out(compared to getting knocked down 3 times before a ko in the other mode). You see how many fighters you can take out before you get knocked down once. The fighters get progressively harder as you go along.
The game also has some random bosses you can get passwords to fight by beating parts of the game. (An example is some crazy 4 armed guy that has 2 arms that can punch u from the top and 2 that can punch ur midsection)
.... This game wont keep you glued to it for long periods of time. But on the go or if u wanna get a quick fun game in before u gotta go somewhere this game is a good choice. If you can find it in a bargain bin somewhere definitely pick it up if u enjoy simple arcade boxing games
