Your second speedrun?
I used to speedrun The Very Organised Thief on my shitty old laptop which couldn't record or take screenshots without crashing. I ran it a lot for about a month in mid-2014, got as low as about 0:44 (iirc) then got bored and stopped playing it.

Superhot was my second game. Lots of fun to run and a pretty high skill ceiling, still doing attempts now of it. All Secrets actually got a new glitch this week and the record was dropped by a minute.
Well let's see. My first speedgame was of course Toy Story 2. I believe after that I did either 102 Dalmatians or A Bug's Life. These were the original 3 that I started with. Although during my early days of speedrunning, I did a lot of stuff so it is possible I'm just forgetting.
