This was my absolute favorite game growing up!
Fossil Fighters is a game I will always come back to with fond memories. I played this game for years, beat it several times, and still love playing it! (And I haven't even finished everything in the game)
The storyline is great, the dialogue is cute and funny, and the gameplay is fun as well. It's pretty simple, you have your sonar and your pick, and you hunt for fossils to revive and turn into a wide variety of dinosaurs to build a great fighting team.
People like to compare it to Pokemon, and I agree they are quite similar, but honestly, Fossil Fighters has always been more addicting to me. The graphics, of course, aren't the greatest, but it's charming, ya know? Plus, I actually like the fighting more in Fossil Fighters. They usually don't take half as long as the ones in Pokemon, which is a relief, but they're still fun and can be totally different depending on your team and how you play the game. And there's commentary! Which is fun to read, though before long you've seen pretty much all the dialogue from that.
The game isn't too hard and isn't too easy, either. I think it's a game that anyone could enjoy!
