I kept seeing people speedrun from time to time, see people practice and do proper runs, and it always felt like it could be a fun and failry competitive way to get back to games I loved and played many times in a new way. In the end, I gave up into that feeling. Right now I am mostly doing Mario Tennis, the GBA version but maybe I will also do the GBC version. But I just noticed a couple of hours ago that there are a few other games I love that actually have a leaderboard and I didn't notice until now. (Luckily, so I just don't do Mario Tennis all the time ahah...)
