There's something about taking old games and injecting new life into them that just seems so fun and exciting! Also very interesting to know that the Animal Crossing codebase has been decompiled into readable C code. Fascinating! So many opportunities to mess with it.
The Ocarina of Time modding scene is growing a lot right now as well if anyone is interested
I recently started playing Wind Waker (HD) Randomizer - so fun! It's almost like playing the game for the first time again.
