I'm really wanting to return to Ragnarok Online just a bit, to really make sure my bitter experience with it was actually just a "me" thing or maybe just a thing in the Brazilian server. But this time in a private server, but there is so many i can't actually decide, if you guys play one and have any recommendation i could check it out.
Also Mario Kart Wii seems to get more and more active and even being updated by the community so i want to check it out
with my totally legit nintendo wii
On another note, i think everyone should check old fighting games, almost all the classics(and even some obscure ones) have good netcode implementation and are easier to play than ever. You will probably find plenty of people to play against too. Check out fightcade or steam ports like for Guilty Gear XX Accent Core +R. Also
https://play.meltyblood.club/ to play some Melty Blood Actress Again for free with excellent netcode and a nice community.
Also, i'm shilling Quake again, the community is active and awesome, after 4pm there is always games, in the weekends it's every freaking day strafe jumping and bunny hopping. Quake 1, Quake 2, Quake 3, Quake 4, Live, Champions, don't matter, the community is awesome, hop in there
