I don't have heaps of disposable time to play them anymore, I've taken up going to the gym, and I occasionally take on extra work that eats into my time...
My enjoyment of games hasn't really waned. I went through a period where I stopped buying things for a while... my brother and I were renting games from Lovefilm up until last August, when they stopped the service - and I think the last couple of PS360 games I played through it were Tomb Raider and GTA V... Wii U and 3DS releases picked up a little over the Summer and I spent quite a bit of money between then and now on stuff I'm only just getting around to completing. One of my 'resolutions' this year is to resist buying new stuff if I still have a backlog of stuff I want to beat.
I'm finding I quite enjoy the tight designed stuff made by small teams. Stuff like Picross, Pushmo, Toki Tori 2+, Edge, VVVVVV, the cave, bit.trip runner 2, spelunky, Knytt Underground -- some of these things I'm late to the party to, they've been out for ages. If I can take bite-size chunks out of them, I tend to like them. I still like the bigger games, but my attraction to AAA games is a bit like my enjoyment for things like Lord of the Rings (except without the allure of good writing). Its rare if I can stick a 3 hour movie on, never mind a 15+ hour game that's mostly all showy crap. The trend of games to try and make some kind of insipid emotional connection or statement feels like a really transparent play for acclaim in my eyes. AAA games either need to make me laugh at the stupidity or rope me in with fun. I still prefer a game that's based around its own mechanics. Things made for fun or made for mastering. If its a linear thing placing me behind a reticule or full of repetitive combat, I find I resent that more and more. Unless I'm really into the subject matter... like, if its the fucking Batman or something.
