Your luckiest win

Starbound pre-order (100 copies)and lots of entries

Mass Effect Collection with 7,277 entries.

Assassin's Creed 2, 6,042 entries

Goodbye Deponia with 3417 entries.

Dwarfs. 10000 copys and 20000 entries. Lol

That's simple, no? Galactic Arms Race 29,740 entries and 25,000 copies to win.

But don't get me wrong, kay? I really do think that this was good game, and I'm not complaining about not winning other games.

The Showdown Effect at 896 entries.

I try not to bid on games with over 1K-1.5K entries if I really don't need the game though (I'll always try for Skyrim, certain indie games, etc.). It's worked out so far keeping me above my estimated wins.

Drunken Robot Pornography, which was a bit less than 2000 entries.
Second place goes to Deus Ex Collection - a little over 1000 entries. :)

Guess that would be borderlands 1 at 1900 entries

Never won a giveaway here, sad but true.

BioShock Triple Pack Private Contributor ($30.00)

BEST GIVEAWAY EVER!!!!

Bioshock - 1244 entries

Galactic Arms Race with 29740 entries... but there were 25000 copies xD

But seriously, they're all lucky wins, unless you're the only entry, in that case it's a guaranteed win.

Scribblenauts Unlimited at 1450 entries.

For me it was Fortix with 627 entries and I has a .16% chance to win.

Magicka, 725 entries lol

Borderlands 2 in a public giveaway with no contributor value...a few thousands entries. I didn't get the gift and the GA maker got suspended. Shit happens.
