I simply can't be bothered with spending more than two minutes learning a game sufficiently to play it any more. Even the tiniest of irritations has me exiting to desktop when in the past I'd have persevered.
I think that's the single biggest problem with gamers today. They simply cannot be bothered to invest any time, effort or patience into it.
I also think playing games has become 'collecting games' or basically just 'shopping', some have dozens of games they'll never play more than once.
I would agree, it's a nasty spiral as well because the more lazy gamers there are the more micro transaction, pay to win, no brain bull **** developers release to pander to the lowest common denominator. People who want challenge are then left scrabbling round for something half decent. Luckily the indie scene has stepped up as main stream is low risk, max reward generic **** (in the main)
