Firstly, there are tons of games coming out for PC, and a gazillion that have been sold in recent years. The myth that 'PC gaming is dying!1!' is nothing new; been around for many years indeed. Still a load of, as before.
Secondly, a gaming PC (that blows away any console, and comes with *unique* capabilities galore) costs nowhere near $1200. Yeesh.
Lastly, mods make a number of otherwise iffy games very much playable. For me, natch. YMMV, etc. But it's worth looking at. Not only are there literally thousands of mods for some games, there are also redux versions being worked on for quite a few old, and not so old, games. Whether it's all about using a more modern engine, or another kind of overhaul. Point is, between mods and remakes, there is a vast 'world' of games out there, only for users of the humble PC. Yes, some mods do exist for other hardware, but PCs get the most and the best of it by far.
