Playing it right now, it's not a bad game, it's just not "OUTSTANDING" because people look at the development time and expect something out of this world.
Designs are hit and miss, yeah, but you can easily make a team of 6 with mons that you liked because there's many of them, graphics are ok to good most of the time, a few handful of sprites are a bit off but most of them are surprisingly well done, gameplay is pretty nice, the game is obviously harder than the official games but not insanely harder, I like this way.
