On summer gaming, when I was a teenager, I'd use summertime like Jonny to catch up on RPGs. Played Chrono Trigger for the first time on PS1 during a summer when I was 16, load times & stutters probably took up half of the time I was playing that game. I tried playing through Saga Frontier 2 a few times, getting tired of it after a several hours both times.
Summer as a middle schooler was always about going outside as a kid. I probably spent more time during the day riding my bike to the local used game store than actually playing games. At night, i'd quietly stay up past my bedtime to sneak in a few sessions of Street Fighter Alpha 3 or get through Shinra HQ on my 3rd playthrough of Final Fantasy VII.
When I was younger than that, my gaming memories revolve around handhelds, taking my gameboy with Mario Land 2, Warioland, a handful of other awful games, and swapping games with other kids as bored as I was while waiting to be done with the outside. If I was home, i'd take my gameboy to my neighbors, and we'd restart pokemon enough times so we could both play the game with all the starter pokemon. At night, I'd play Sonic 1 or ToeJam & Earl for the 1,000 time trying to inch my way farther in the game to see if I could get to the end.
As an adult, it's not difficult for a job and family to consume the majority of your time. Over the weekends in the evening I may get to sink my teeth into a meaty action game or churn out a handful of MarioKart online games, but otherwise the week only leaves time for more bite-sized morsels. This is partially because of having smaller kids that require a lot of attention, but I wonder how much time I'll eventually get back to be a bit more self-sufficient.
