We've experienced alot of games and have nostalgia with the older games, it's quite difficult to stay motivated and patient. people make the same mistake of giving up a game within a day or a week tops, you will run out of games to play fast if you keep doing this and there aren't going to be many games that can replace the best game of your life. (the new ones are honestly overhyped garbage..)
master x master http://www.playmxm.com/en is similar to battlerite or your traditional moba (based on what arena mode you chose, you can skip either ones if you dislike moba etc)
you move with wasd keys unlike league of legends and control upto two characters that can be tagged when you're low or against a counter element (fire > grass > water > fire)
it has pve content and you can get rare mods at the end of the result screen based on the difficulty.
try joining a guild, and their discord chat, have fun talking about random stuff and play with the group to stay motivated in your games.
sometimes i revisit old mmorpgs that i've played when i was a teenager, it's always nice catching up with your nostalgic friend again! :3
