You are probably right, it is a good time for PC's and the indie game revolution is really helping a lot too. As is the love for mods that is spreading, and I love Steam sales too. Although I have always been a PC player by choice, I've played one for 30 years. There are a lot of consoles I could have had in that time but I chose not to. For me there were a few bumpy patches. The SNES was one of them because that had some games I really wanted to play and I couldn't, although I ended up borrowing a snes to get my fill for a week and eventually I could play some of those games on an emulator on my PC anyway.
Since then though there are no games I wished I could play, especially since the xbox/playstation era, I just don't see any of those games I would want to play, and yet so many PC games at that time which were exactly my cup of tea. (Tiberium Sun etc). The only other time was several years ago when stuff like Red Dead Redemption was getting hyped and it wasn't on PC, and then GTA4 released with no mention of whether there would even BE a pc version. Also my graphics card, cpu and ram were all ageing, and a cheap console had finally become a lot more powerful than my PC. I think Alan Wake was hyped to be an uber PC game game too and then ended up going to consoles first. There were a lot of articles about how the PC was going to die at this point too, and the rise of tablets were taking a huge chunk out of the PC sales business. It had me worried. But still, I preferred my PC because I am an MMO fanatic and they are mostly unique to PC's and they trump everything, also I play occasional shooters and for me it is mouse and keyboard or nothing. Also I like RTS, which again is all about PC, and certain RPG's (Baldurs Gate etc), and then there are a lot of old games I like to play which are PC only too (and things like Magic the Gathering online). And then a lot of those console only games, once the hype died down I saw a lot of people talking about how they weren't all that special anyway. And after all that, Alan Wake got dumbed down into some generic survival zombie horror game when originally I thought it was going to be an awesome Steven King adventure game or something.
Long story short, I've always been happiest with my PC. And then I got into Arma2 and Arma3 and I play that game pretty much constantly in a state of awe.
