which game you regret buying during sales?

Not including this sale only... Probably most of the things I bought from sales then.

I regretted buying Guns of Icarus Online. When I saw the gameplay, it was really good but when I actually tried it, it wasn't as good as I expected it to be. But then, I requested a refund for that game so I guess it wasn't that bad after all.

Bought nothing..regret nothing

Nether, 80% off last year

Probably 100% Orange Juice because I don't want people on my friend's list to think I'm a weeaboo or anything.

this is not the time to regret. a week later at the middle of night when you can't sleep then for no reason you go to sites then it's time to weep n wonder why did I ever get games on this sale when I haven't touched games from last sale..

Total War - Rome 2 - Emperor Edition. Thought Emperor Edition meant it was a sort of complete version...it wasn't, none of the DLC was bundled.
Luckily for me the new Steam refund system actually works, got my 15 bucks back (after 4 days).

Don't regret the 30-40 other games I bought since if any of them was a mistake it's a mistake I would have made sooner or later anyways.

Well, I only bought WWE 2K15. And I get to choke slam people in that game so... 0 games regretted.

Good thing we get refunds now

I wouldn't call it a regret, but I'm not enjoying Valkyria Chronicles as much as I thought I would have. It's an excellent game, but not entirely engaging for me.

LOL did regret some, asked for refund, got refunded %)

I don't really regret any purchases, because they were almost all giveaways. I did have to refund sleeping dogs definitive, because it's banned in Germany. I can't do giveaways for games restricted like that.

Bought Need For Speed Undercover, Hatoful Boyfriend and Slender The Arrival. Also got Wolf Among Us from Tremor Games which kinda counts.

NO REGRETS.

bought about 50games, never regret love to collect :) then again if i ever play them will be a big mistery :)

All of them. Steam likes to steal my money! Maybe i'll actually get round to playing a few of them??

2 regrets. Refunded for one, second in progress.
Love the new refund system, feel much more secure.

Banished, but I already got refunded so no regret.

7 days to die :/

I regret nothing

None yet. Ask me in few months, when I realize I haven't played most of them yet XD

It's the first Steam sale for me, but I got a few games from my wishlist and they were good deals, so can't really complain. The Witcher 2 didn't make a good impression on me, but I only played the tutorial through so it'll be probably way better experience later. So, nothing to regret, but I didn't have any games on my wishlist that got their prices increased by miracle before the sales..

None... yet. I haven't actually played any of them yet >_>. Saving a few of them for later this summer (mainly, Wings of Vi)

I only had limited funds this summer, so I only bought the games that I really wanted. So no regrets here.

I regret nothing. =(^..^)=
