Entering GA you once gave away

If you don't own the game you can enter.

As long as you do not have the game in your Steam library. You are free to enter I am to assume.

Dont see anything wrong with that

Definitely should be fine.

I can see why you're asking though, this community confuses me.
People apparently blacklist others for leaving comments that say Thank You on a giveaway, so who knows, someone would probably find a way to be upset about it.

It's fine as far as I'm concerned, definitely not against the rules and most people shouldn't have a problem with that.

I've seen this discussion before and there were people saying that they frown upon it, but personally I see it as perfectly acceptable as well...

EDIT: Wait, I think the discussion before was about about entering a GA for a game you have in the inventory with the intention of trading or making a GA... Anyway, my point stands :)

It seems normal !

All right most of the people tend to be fine with it.

There are a few that disagree but that's only natural.

for any package:
if you own the games then you are an asshole and probably get blacklisted if spotted.
if you own more than 50% of a package and you enter just for 1 game or the DLC then again you are an asshole and will probably get blacklisted.
if you own <=50% of a package then you are not an asshole but some ppl may have different opinion.

Sure :)
Then again I've found myself in a similar position before: winning a game in a GA and then buying a bundle with that same game, then trading/ making a GA for that game. I think that looks much worse from the outside :x

This is something I have always wondered myself. A few games I gave away that I should have gotten a copy of for myself on the sales.
