>>55832856I've been stuck coming back to this game and still haven't played gen 2. Normal playthroughs, solo playthroughs, nuzlockes, glitch exploration. I really like what you can do with Missingno. and 8F (Arbitrary Code Execution (ACE). different routing skips for speedruns, reverse badge acquisition, etc. On my glitchless playthroughs and nuzlockes I like to battle Prof. Oak at the end. (Yes, you have to glitch to do it, but I only glitch after beating the E4 and only what I need just to get the battle.)
I also like messing around with the PokeRed Disassembly Project from Github.
The battle system being so different from the othere gens and the crazy stuff that you can abuse make it really fun for me. That and the bugs in the battle system.
