Finished 28 last night. So 28 beat out of 38 played I think.
Now that I'm more than halfway through with the 52 game challenge, I've made some observations about myself.
Prior to taking part in the 52 games challenge, I would strictly play games based on whether or not I actually wanted to play the game, occasionally I would play for achievements. So I would maintain a gigantic backlog and I would spend more time deciding on a game to play than actually playing games in most cases. But when I did pick a game, I would play it until I was bored and never play it again, or I would play the game fairly thoroughly until I was tired of playing it.
But now, I'm noticing that I'm knocking out more backlog because I'm not thinking about what game to play, I just play something. But on the other hand, I'm also basically speed running these games, doing very little side stuff and just playing to get the credits to pop. There are exceptions, quite a few games I liked so much that I spent way more time than necessary to pop the credits. But a game like Retro City Rampage DX, I played through it very quickly, did 0 side missions, and just ran through the story and wiped my hands of it. A game like Fallout 4, Rise of the Tomb Raider, Capsule Force, Party Hard, etc... completely random games, I spent tons of time on these games doing tons of side stuff and trying to unlock everything. Without the 52 challenge, I may not have played Capsule Force or Party Hard, but I would've played Fallout and Tomb Raider regardless. I definitely wouldn't have forced myself to finish RCR without this challenge.
tl;dr I'm bursting through backlog like crazy, at the cost of putting a lot of effort into the games.
