I bought it, and honestly, as a big TR fan, I think this is the finest game in the series based on my early experience with it - the Wii version specifically. It's pure vintage Tomb Raider gameplay, through and through...tons of platforming, tons of large puzzle/switch areas to keep you on your toes, and some shooting to fill in the cracks.
While the camera often feels close-to-broken, the Wii version happens to have an EXCELLENT means of camera adjusting (holding C and moving the pointer - or just pressing C to reset back to behind Lara). So after you play the game for 15 minutes, the camera is no longer an issue - it's so easy to position it exactly how you want it, or to just naturally reset back to behind Lara when things get wonky.
Shooting feels excellent. Aiming is smooth, and is certainly a nice touch compared to just locking a target and pressing a button. Locking the camera on a target is quick and easy, and using the Nunchuk gesutre to dodge an enraged enemy feels completely natural.
I'm still pretty early into it, but the little puzzles that make use of the Wiimote functionality so far have been OK. Not great, but a nice added touch...something I prefer to have than NOT to have.
So yeah, overall, one of the finest purchases I've made this year. All of the gestures and Wiimote usages are so finely done that it feels completely like a ground-up Wii title, and that's the truth (though, graphically, while it looks totally fine, it's essentially identical to the PS2 build). It's a shame this has led to some hit-or-miss reactions from reviewers, but I personally wish every Wii developer gave PS2 ports this sort of treatment - to make them FEEL like bona fide 'Wii' titles.
