EVERYTHING I've heard about Elder Scrolls: Oblivion has been that it's an incredible game, so I would definitely suggest it if you like RPGs. For the Wii, I would suggest Legend of Zelda: Twilight Princess, which is (in my mind) the best Zelda game to date (OoT is second). I myself am a fan of RTS games, so games like LoTR: Battle for Middle Earth 2 are a good way to spend some downtime; Star Wars: Empire at War is fun if you're a Star Wars nut like myself xD
