If your 38 you can scale back on the twitch reflex bash the buttons type games, it gets repetitive after a while.
Sounds like you might need a game with a story or some grander purpose to it so yea you officially old and should light a pipe, slippers and a plate of crumpets before any gaming is done.
I was speaking to someone 58 earlier in a mod for bf2. Those games are measured in hours, its definitely a slower pace so kinda fits your post there.
I dont think crysis was bad but it wasnt a classic, if the graphics or physics didnt impress the gameplay wasnt anything new or special, it definitely ranked as a 'good' game though
Bioshock has a decent story, quite a few people liked its design so your pushing the limits of mainstream games in your leisurely pace no doubt. (I wasnt that fussed on bioshock fighting either though)
I thought HL2 was excellent. Im going to go in the opposite direction and recommend left4dead and if that doesnt work its going to be something very particular or a sports game if thats your thing
the thing with reaction speed is that it improves vastly depending on how many hours you clock on that particular game, as well as other factors such as sensitivty of your mous
e. More you game, the more pro-like you'll feel. my 2pence.
it also favours teenagers as reflexes are literally fastest when young. Also technical crap like latency network times, its not gameplay really. I dont think the OP wants to be 'pro'
