Clearly the best roleplaying game on Wii so far.
You don't just get better by collecting better equipment, but the biggest factor here is skill. Monster Hunter series is all about skill and Tri is not different. It's quite challenging game, that requires staying calm, and planning the next move carefully. This is not a button smashing game. Simply blindly attacking anything, will end you up dead. Basicly progressing through equipment, learning and mastering the game, makes Monster Hunter Tri an absolutely addictive game.
The visuals are what you would expect from a Wii game. It's beautiful, but still lacks a lot of the power PS3 and X360 have. It's still the best looking Monster Hunter game out there.
