Sure, it'll cost more than a console, but the games cost a lot less
This is probably the best argument for PC. I've got so many amazing games on Steam and I've spent so little. And I mean triple-A games, hugely acclaimed games ,sprawling games, everything, often for ~$6 for several of them at once thanks to all the bundles you can find around the internet. Then Steam's sales—not even their Summer sales, but just the sales they have weekly—make it really hard to argue that a PC is more expensive. If you buy games, you are doubtlessly going to save a huge load buying them for PC.
also i should point out i have all these games on a pc that can't even play them, that's how good and impossible to pass up these deals are. When I do get a good PC...oh lord I will have so many games to play.
Also, really, Nintendo has the only consoles worth getting, IMO. They're the only ones with experiences you consistently can't have on PC, partly due to the exclusivity of their games and partly because they try new things with the consoles themselves. Whereas Sony/Microsoft will have intermittent exclusives, Nintendo is guaranteed to have a ton every generation, if mostly because their first party games are wonderful.
So that's why I'm probably just going to stick with my Wii U and 3DS this generation. I don't see any real
need for a PS4 or a One. I might grab one in a year or a few years from now when they're cheap and have exclusives that aren't worth passing up. Until then my money will be better spent building a gaming PC.
Also, the "exclusives" issue with PS4/One
might not be an issue this gen.
