Just started a save in Red++ (a ROM hack of Red). So far it's not too different from the original, but I'm enjoying it. You can encounter a few Pokémon from the next generations right from the start of the game (like Zigzagoons in route 1), which is nice. The graphics have been improved and look a lot more like the gen 2 games on Game Boy Color.
Also started a nuzlocke in Emerald, in which my Grovyle got killed by the Dewford gym leader's Makuhita... So I had to restart and this time I picked Torchic and immediately caught a Lotad in route 102, which should facilitate my battle against the first gym leader.
After these two, I plan on going through:
- Shining Pearl & Legends Arceus, of course
- Platinum (nuzlocke)
- White, since I barely played through the gen 5 games, so I want to give them another chance.
- Unbound and Light Platinum, which seem like nice ROM hacks
