In short, controls are really good. Graphics are definately sub par compared to the xbox version.
"Enter Far Cry Vengeance. This game goes a long way toward proving the potential of the FPS genre on the Wii. While Ubisoft is still making use of the bounding box technique featured in every FPS so far on the console, there are significant enhancements to the control setup, elevating it over its counterparts on the Wii. Upon booting up the game, the first thing we noticed was just how responsive the control was compared to other titles out there. It was only a matter of minutes before we were cruising around the jungle, popping baddies in the head with ease. During our (admittedly) limited play time, we never once experienced the control glitches that we have with other shooters on the systemi. The game never lost track of our Wiimote, and the reticule always stayed exactly where we were pointing it.
The biggest addition to the control scheme is actually something that seems minor on the surface. Holding down the "A" button holds the screen steady, so that aiming around the screen does not turn your character's head. In practice, this makes quickly aiming at several enemies in succession easier than ever before on the Wii. This is also a boon for the game's driving sequences, which make use of the analog stick for movement of the vehicle and the Wiimote for aiming. Without use of the "A" button, we found ourselves aiming wildly about our surroundings, but while holding it down, our accuracy became perfect allowing for a much more pleasurable experience."
"Far Cry fans out there had better ready themselves for a decidedly uglier jaunt through Jack Carver's shoes than on any other console. Ubisoft obviously put a lot of their efforts into pushing the draw distance in the game rather than polygon count or texture detail, and it shows. When moving quickly, the jungle seems to have all of the detail as in previous Far Cry games, but as soon as you stop moving and look closely, a distinctly muddy look surrounds you.
No one is disputing that the Wii lacks the graphical bells and whistles of its competitors, but that doesn't mean that Wii games have to look worse than Xbox or GameCube games. Nevertheless, several Wii games do. Compared to Far Cry Instincts on the Xbox, Far Cry Vengeance looks fairly awful. Textures everywhere lack detail, and the framerate often dips below 30 fps. Furthermore, the overall polygon count is quite low, making for some awkward looking enemies and environments. Thankfully, the draw distance in the game is impressive, helping it retain some of the visual flair of previous Far Cry titles."
Isn't that heart-warming.
