May be I'm wrong, but I think you used to be PC-only gamer, really odd game list.
My vote for Metroid Prime 3: Corruption and The Legend of Zelda: Twilight Princess - both action-adventures, differ from each other in any way, both worth playing. Zelda always used to be very accessible for almost every gamer, so if you played it enough you wouldn't stop till the end. Metroid not so good at this point, not for you if you don't like high level of backtracking, this game seriously not about shooting things. Nothing new comparing with brilliant Metroid Prime (2002), but there're not so much games of this type on the market.
There're a couple of other games from 'excellent' to 'mediocre', but rest depends on your tastes: Battalion Wars 2, Fire Emblem: Radiant Dawn, Mario Kart Wii, No More Heroes, Super Paper Mario, Super Mario Galaxy, Super Smash Bros. Brawl, Tales of Symphonia: Dawn of the New World, Wario Land: Shake It!, Zack & Wiki: Quest for Barbaros' Treasure etc.
