Sega's been getting better lately....Virtua Tennis, Virtua Fighter, Secret Rings, Monkey Ball, the Total War series, Crush, not to mention a lot of their upcoming stuff is looking incredibly promising. Universe at War, Virtua Fighter 5 Online, Sonic Rush Adventure, Sega Rally Revo, Valykrie of the Battlefield, and now NiGHTS.
Sega's been going through a lot of growing pains since they went 3rd party, especially after the Sammy merger. It's been pretty obvious going by their rhetoric, that they realize they've been giving us a lot of crap lately, especially via Sonic, and are now ready to change it up and give us something good.
