I has four glorious moments where I've wanted to do this.
* Square Enix. Mostly for making Front Mission Evolved (which rightly ranks as one of the worst games I've ever played). I could not think of a worse entry point for the Front Mission franchise for a newb than Evolved. Awkward Controls (even tuning the sensitivity on my mouse as low as it will go doesn't create a natural aiming feel), painfully cliche and predictable story that basically made me thought someone on the Dev Team had played too much Armoured Core 4 Answer...and the Wanzers. Seriously. Do I need to cite all the jokes Unskippable made about them?
* Electronic Arts. Various points, but most infamously Red Alert 3. I have never seen the point so sharply missed by anything else in existence. Essentially, what had some sense and was genuinely funny at points (and didn't overplay the humor) got replaced with a mix of Racism and Crack. For the record, I didn't think Tiberian Twilight was that bad (the crawlers had potential, but it was a poorly executed concept), but the Single Player Campaign makes me beat my head on the hitting end of my Thunder Hammer.
* 1C Company. They're like the Russian/Eastern European version of EA. They have very high quality ideas and concepts, and some interesting gameplay mechanics...on paper. When it comes to the game, they're executed very, very badly. And don't get me started on sequels for their games (case and point: Perimeter).
* Activision. They seem to have a real stigma against PC Gamers from what I've seen. Specifically, their Downloadable Content policy. Looking around on Steam, CoD: WaW had NO Map Packs released, while it's console cousins had somewhere around 3 or 4. But it's not just CoD I've noticed - none of the DLC for Transformers: War for Cybertron (which Activision published) has made it's way to PC either. So if you want some cool new maps for Escalation, or to play as Shockwave or Jazz, you better have a Console sat around somewhere...
