I've occasionally expressed a wish that I'd spent more time in my younger days playing Game X or Game Y, but it's been pointed out, for every game I didn't play, there was likely another game I was playing instead. That's probably true. Back then, I played a lot of games and so, if I didn't play much RuneQuest, for example, it's because I was likely too busy playing something else.
So, here's today's question: are there any games you played a lot at one time that, looking back on them, you wished you'd played less, so that you might have played something else instead? In truth, I have a hard time thinking of any game I played a lot way back when that I regret having played. There are a handful of games I played briefly that, in retrospect, I don't think I'd miss if I'd never played them, but those are few and far between. Much as I regret not having taken more notice of some RPGs back in the day, I don't think I'd trade in the large swaths of time I spent playing D&D, Traveller, and Call of Cthulhu to have done so.
How about you?
