I don't game much because I spend most of my time buying games on Steam
Multiplayer games have become very popular with me in recent years but it's nice to escape and play a deep story-driven game once in a while.
I tend to avoid games that are short. I'm playing games more frequently and for longer periods than years ago and some games can be done in just a weekend over 5-6 hours. Back in the day; games like Goldeneye I could piss about on for months and not get bored but my expectations are higher now and with me and others playing more; if I go for a single player game; it has to be on an epic scale like Skyrim. £40-50 for a measly game in this day and age and with money; ain't worth it.
I love FPS games best but strategy, sports and RPG's are massive genres for me. I mainly play MP on shooters because of their longevity and infrastructure. Usually they offer more depth than the likes of GTA and you can really have a few good sessions on them. Civ and Total War are fantastic games I like in the strategic area and any RPG's whether being an MMO, single player or niche like survival games are also on my hit list.
I still go back to classic games like System Shock 2 and I always keep my eyes open on Steam for any games that come out of nowhere. I tend to avoid racing games now though. After GTA; racing just doesn't do anything for me now. I used to play Gran Turismo on the PS1 and that lasted me years but half our on the likes of Forza and I just wanted to get out the car and shoot someone.
Work and football gets in the way sometimes but there's always plenty of games to play and keep an eye on. Except on the Xbox One
