I think it’s really impressive what the community has done with Super Smash Bros. Brawl. Project+ is basically the current “flagship” modpack. It builds on Legacy TE (which is built off Project M), so there’s loads of new content and more Melee-like gameplay.
Another Brawl mod I like is Brawl -. Its main thing is that it balances the game by making everyone’s movesets overpowered.
Changing genre completely, I really like the Gay Awakening and Gay Fates mods for Fire Emblem: Awakening and Fire Emblem: Fates. The main thing the mods do is add new romantic and platonic supports to the game. The focus is, as the name implies, on adding gay and lesbian content, but it also adds straight content to a lesser degree (like for the characters that can only support with Robin or Corrin).
I have a Thinkpad T480 that I’m very happy with. I believe it’s around 7 or 8 years old, but it works great. Unlike most laptops, it doesn’t have soldered RAM, so it’s easily upgraded. One downside is that most units don’t come with a lot of storage, so you’ll probably want to get a larger drive. I spent around $200 on mine plus another $100 for the SSD. It’s a great inexpensive laptop that’ll last for years.
