Late to the party, but I was gonna suggest geometry wars... infinite replayability and fast paced action, you can't go wrong with that. Ah, check out Pacman CE... one of the best games available on XBLA.
As far as XBL gold being worth to you, it depends on how much time you are gonna pump into it. You'd play maybe 30 hours a year online, are 30 hours worth 50 bucks to you? etc.
Current-gen game collection uploaded on the profile, full of win and good games; also most of my PC games. Lucasfilm Games/LucasArts 1982-2008 (Requiescat In Pace).
