I don't think this is really a discussion, but more a 'look what I found' topic.
But I'd say none, as long as you're enjoying yourself go ahead.
Yeah but it can be both as well, hopefully :D
Seriously though I've had many friends tell me I'm too old for this. People ask me casually which $500 smartphone to get and look surprised when I tell them to buy a good GPU and play some games. Like, its culturally ingrained in them that games are for kids only.
Pokemon is good. Anyone can play it. It actually has very deep mechanics. Whether I play it or not is irrelevant compared to the fact that Pokemon is most likely the worst hit of all as far as being branded as a kid's game is concerned. Just look at the battle simulator for PC and you'll see how complex and skill driven it is.
