(my weapon > your weapon)
My weapon > any weapon in your game
I finally got around to playing Tri today. As far as a port to a completely different rendering and gameplay engine goes, they did alright, but the fact that they left out Gunlance, Dual Swords, and Hunting Horn (did they remove bow too? I forget) makes it a pretty worthless game, since those are the most fun weapons to use IMHO.
If you want to play Monster Hunter, pick up a PSP and a copy of MHP2ndG and MHP3rd. MHFU is good too but missing some of MHP2ndG's content. Tri's the worst game in the series that I've played to date, primarily due to the limited weapon selection, view smoothing (aka view lagging), and a lot of the monsters being removed from the game. It's not a bad game; just not nearly as good as other games in the series.
