I play a lot of games at once because what I want to play is based heavily on my mood. But I try to limit myself to one game per console, although that doesn't always work. I used to just play as long as I felt like it and then switch it up but I've pushed myself to complete games this past year, so I'll play them to completion. I usually don't play series back to back, which is why my Suikoden Marathon is a thing, because it's not usually something I do. I tried a Xenosaga marathon a while ago and only made it halfway. As far as new games, it depends on cost and how excited I am for it. Like a lot of 3DS games were $40 new and it's over a year later and they're like $37, if I'm that excited I'll pick it up right away instead of waiting a year to save $3. If it's a game I'm kind of interested in but not super excited about I wait for price drop
