Just like the weather, the Wii lineup is heating up this summer with a wealth of promising games. Third parties are coming stronger than ever before with such potential hits as the new online-enabled Madden and the DDR-style karaoke-enhanced effort Boogie. Nintendo is no slouch, either, delivering some of its biggest hits, from Pokemon Battle Revolution to Mario Strikers Charged. IGN thinks Wii fans will agree, however, that this summer belongs to Samus. That's right -- the return of the Big N's bad-ass heroine bounter hunter in Metroid Prime 3: Corruption. With all of these games, there's no reason to go outside.
