Did you ever bought a game on steam without any reduction ?

From bigger titles Control, Fall guys and Days gone, but DG I maybe got on 10%, I don't remember. Also if something interesting from my wishlist release with price under 15€, I don't wait for sale if I want to play it. Other cathegory are old games from my childhood like Freddi fish or Swords and sandals. I just were in mood to play it, so I bought it.

I've purchased many, many games at full price and even (gasp!) pre-order games all the time.

Horizon Zero Dawn
Persona 4
Football Manager 2016
Football Manager 2020

Well most pre-ordered games usually have discounts, so ... ahem, no? ^^
I'm currently considering Football Manager 2022 or Forza Horizon 5 as my next purchase.

Cookie Clicker

Bought at full price only The binding of Isaac: Rebirth and its dlc.

no, but my friend bought me a few games that were for the full price

I'm broke af, so I'm wating for those discounts
the only game that I bought with a full price is R6S

the only full price game I bought was valheim, never bought a 60€ game.

Mini motorways

Cyberpunk is the only game I bought with a full price

I can't recall how many times, but I did buy games at full price if I really wanted the game as it came out. Normally I paid lots of attention at the price. If it was in the £5-30 range, I'm more likely to buy it. If it's beyond that I'll wait for a price drop.

Last game I can recall was Valheim, Foxhole and Foundation that I can recall.

Over the course of years, I surely bought more at their standard price to support the Indie developers for their amazing game developers. AAA games are always expensive once they come out, so I need to make a calculated decision if I want to buy it or not.

Without any discount? Probably none on the PC. Think the last game I pre-ordered on PC was Sniper Elite III and that was with a good discount. On the console side I have paid full price for quite a few Nintendo games, mostly because I generally know what to expect, and they don't normally have much discount for the physical copies.

I probably don't remember all, but a few off the top of my head are:
Cyberpunk 2077 - The game was a bit of a letdown (meaning it could be something way greater than it turned out to be) but still enjoyed it a lot and did not regret buying it
Valheim - In early access. I have almost 500h in the game and enjoyed it a lot. Totally worth the 20$ I spent on it
New World - I wanted to get in early since it is an MMORPG. The visuals, audio and atmosphere is great but the game itself is way too grindy. I still enjoy playing it despite of it but I'm not sure if I still would get in on it.
There are a few more which I probably brought early on but not from steam with a small discount from somewhere else. (If I remember correctly a few of them was A Plague Tale: Innocence, Vampyr, Middle-earth™: Shadow of Mordor, Middle-earth™: Shadow of War™) and I really enjoyed all of them.
Most off the time I only buy games at full price that I really want to play and play them right away despite my backlog being really big.

Yes. Milk inside a bag of milk inside a bag of milk and The Binding of Isaac: Rebirth is that game ever discounted?

Age of Empires series (And age of Mythology) Completed all of them. However, sometimes I regret buying games with 20-50% off and not playing them soon because they will be more cheap in future.

No, how could I? I am so old, I remember a time when games were available as physical copies. Digital crap is not worth paying full price, as long as you can' resell it.

The Great Ace Attorney. I love the series and I want them to bring them all to steam D:

One game I can remember buying at full price is Monster Hunter World. I received more than my money's worth with that game and its Iceborne expansion and cosmetics. Technically I also paid the full price for Subverse during the Kickstarter campaign cause horny; still waiting to play that game when it comes out of Early Access.

No, never. I never bought game at full price and do not plan to do it ever.
I start considering buying at 75% off. Eg i bought Fall guys at 50% (idk why) off and still regret cuz i played like 2h :D that should be exact reason why i dont buy it at expensive tags

The only game on steam that I've not gotten on sale was Starpoint Gemini Warlords, though it was early access and cost less than at release.

Battlefront 2 (classic) on a whim because friends were playing at the time. Only ended up playing the one session and already had a copy on PS2 to play alone, oops.

i think i bought my son a card with the code for stardew valley on it - not really on Steam per say but he really loved back to nature and it was a birthday present (before it got bundled i think)

There were a couple of $5 indie games that I picked up at full price because they never went on sale and were unlikely to be bundled. There was also a game that I bought on itch.io that included a Steam key that I paid MORE than the price on Steam simply because I wanted to support the dev.

RimWorld - because it's never on sale.
Fallout 4 - on pre order (to be honest someone bought it for me).
Bunch of games for people (have no idea how many) in my group (Quality Games Giveaways) - as rewards in various group events we had.
