RVDondaPC: Nothing is different besides a few encounters. They are basically the same game.
naznatips: MHTri will have less content, and the online issue can be resolved through having a PS3 with Ad-Hoc Party or a computer capable of using X-Link Kai. P3rd will recover some old monsters as well as the old weapons, that alone gives it more content. It loses (possibly) 1-2 of the monsters Tri had because they are mostly underwater monsters (Gobul and Lagiacrus), but otherwise P3rd will have more content.
