Instead of improving on the interesting monster training systems of the first game, Digimon World 2 just tosses out the tub and the water and replaces it with a pretty standard Mystery Dungeon esque game. The game does a poor job of tutorializing basic things like how to capture a Digimon, evolution, and even how to add items to your inventory. It's funny that they decided to keep that from the first game even when Digimon 2 has been vastly simplified. It looks nice and the music is alright. The biggest detriment here is just the pace at which it moves. Battles move at a snail's pace due to the animations which quickly grow repetitive just due to sheer number of battles you'll be fighting. Making progress in the game is just not that fun. Honestly, if they had taken this concept to the GBC/GBA where it could have been scaled down and sped I could see this being a fun game to play on the shitter. On the PSX, while visually impressive especially for a budget title, it's just a drag to play.
