A hell of a lot. :D 2 consoles, a Pro and an Elite. An extra controller, tons of MS points, 2 yearly subscriptions to Live so far. TONS of games, looking over prices...

Gears was bundled with my first console. Tomb Raider Legend was pre-owned at £25 because I couldn't find a new copy. GTA4, Both Rainbow Six Vegas games, Mass Effect, Saints Row, Crackdown, Lost Planet, Halo 3, Turok, Fight Night 3, Lost Odyssey, Pro Ev 2008, and lots more were bought at full price. Saints Row 2 was £35, Lost Planet Colonies was £20, Prey was £10, PDZ was £15, and a few more were bought for less than full price. Either way, I'm still talking many hundreds of pounds on retail games.

Are people counting multiplayer as "replayability"? Obviously any time I play Halo 3 online I'm "replaying" it. But to me the phrase means doing the same thing over, i.e going through the single player again. I practically NEVER "replay" a game in that sense, don't see the point. I've done the story, completed the narrative, and that's why I bought it. At that point, the game should have already justified its own purchase. Being asked to unlock content, or collect X amount of Y objects just pisses me off, I don't like the crap that Devs hit us with in an attempt to create replayability. Some games are enjoyable enough to do some parts of the SP again, like the T-Hunts on Rainbow Six Vegas. But overall, no replay value means nothing to me.

I don't sell the games because a) I'm not cheap and b) I REALLY don't like the used games market.
