Usually.

Only for games where I am really really hyped for.

Most of the time, guess it depends on the game too how much anticipation i have for it.

Yes, my most wanted ones. Next day 1 purchases will be Sam & Max (Wii) and Prof. Layton (DS).

No. I think I've only done it a few times before. I think I got Street Fighter 2: Turbo for the SNES right when it came out, possibly the first day. I also got very excited for Mario Kart DS so I actually pre-ordered that and I think I also bought True Crime: Streets of LA for the GC since I was interested a GTA clone on a Nintendo system.

Generally though now, I won't buy a game first day. I like to see plenty of reviews and even fan reviews, Games are too expensive to buy just on hype alone.

Oh I also bought Super Mario Galaxy first day because I was sure it would be a great game and I think there were already reviews online saying it was excellent. And I bought it at Toys R Us which had a great promotion going on if you bought the game. They were giving out a $25 gift card along with SMG so that was a steal.

as a rule of thumb I buy titles day one if I anticipate them for more than half a year.

I pre ordered fable 2 that one and gears will be day one purchases for me

More often than not. This gen there is no game I have bought more than a week after it came out and about 85% of the games I have bought have been day 1.

typically no. If I pre-order them, I now order them from the VGChartz store to help out the site. Amazon ships for free, and it only takes 2 days to get where I live (its nice being near a distribution center)

As I wrote also in my profile, I'm so far behind in my gaming schedule (alas also in my studies ) that I buy almost always games when they go budget. Gaming on PC this also saves me from bugs, besides from crappy games.
