Want a 3ds but im afraid i wont play it?

It seems like everytime i try to play a videogame i quickly loss interest and i stop playing. Ill usually only dip an hour or two in and end up never going back to it. Could it be my age? Maybe with priorities changing and all? Or could it just be the lack of games that peak my interest?

Skyrim, minecraft, are some of the few games that had me actually wanting to play. Mostly minecraft though. I have a lot of fun with that whenever i do play it.

So should i buy a 3ds?
