In my case it is Batman Arkham Knight at the premiere on PC... this port was probably the worst ever happen on PC makes it completely unplayable on any device and everyone must wait like a year or so to get a proper optimization :/
"agricultural simulator 2013" - Bought by mistake, I decided to play but I did not like it.
I regret that I didn't do it refund, i was to buy then "Farming Simulator 2013".
Orwell: Ignorance is Strength - I loved first one, really nice concept of a game but sequel didn't have this one special thing that first Orwell had. Maybe it was a story (first one was amazing and you have two different endings - the second one I think it's only one ending), maybe it was another one game with same mechanics or maybe just I loved the first one for being something new and the second one is just created for money.
Lost Planet 3 Box, bought for 10$, didn't played, 3 months later it was in HB for 1$. That opened my eyes and i stopped buying like crazy.
Endless Legend is my worst purchase.
Season pass for Assassin's Creed Unity........ there were no season pass.... just some "freebie" game from Ubisoft and Assassin's Chronicles China........ worst deal ever.
In terms of "not the most expensive, but didn't liked it, will never play again" - Chivalry
"Bought for the full price, never played much, got bundled" - Endless Legend
Diablo 3 & Reaper of Souls. I mean it's not bad game at all, just I paid full price for both base game & dlc and I only finished campaign twice, nothing more, because end game was soooo boring for me.
Bulletstorm, game wasn't bad but I paid full price for 6 hours experience, without proper multiplayer.
Space Hulk: Tactics game isnt bad, but not worth the full price (for me).
SimCity 4 Deluxe. A piece of trash 🙁
Crusader Kings II and Europa Universalis IV. I bought the base games and then some dlc, and then some more dlc and even more dlc, all the time promising myself that I will finally play them when they stop growing, but they never do...
Payday 2, due to ugh....
can't buy partial DLC now, you've been forced to buy ultimate edition which kind of over cost over DLC i'm missed ._.
Biskuit I think price of the ultimate edition is calculated depending on the missing dlc, no? Anyhow I managed to snatch a few missing dlcs right before they removed them from the store. Not that I actually play that game, just for collecting purposes. 😃
pb_ sadly nope, it's not like other "steam bundles" but it just kind of new game
for example, i only missed around 3$ worth dlc, but ultimate edition cost full game price ._.
Biskuit Well that's certainly not what they advertised:
"How much will PAYDAY 2: Ultimate Edition cost?
PAYDAY 2: Ultimate Edition will cost $45. Discounts are automatically applied to anyone who already owns PAYDAY 2 and any DLC."
also according to steam it is a "complete your set" bundle: https://store.steampowered.com/bundle/3756/PAYDAY_2_Ultimate_Edition/
pb_ since i got regional prices, it seems around 15$ right now, when it launch first (the ultimate edition) iirc it's cost around 30$+ tho maybe they changed into steam bundle mode now, still it won't change the fact it's still the worst purchase for me due their bad marketing ~
Fair enough :-)
There were a few that looked very nice at the Steam video, and then it turned out that they were bad, but I don't remember the worst one.
The first Assassin's Creed game was my worst purchase ever. I tried to like it (enough to finish it) but I was super bored with it after few hours.
