Pls Pls Pls PLs Pls Pls Pls aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Pls why everybody igores me

sorry if i didn’t reply before as i was sleeping. but to answer your question, citra online is kinda like a chat based place where you can hangout with ppl. some games have their in-game features linked to online play so say, i wanna trade pokemon. then i can join a room and all the ppl in the room will show up as their trainer variants (only if they are playing the pokemon game ofc) many other games use this too. animal crossing: new leaf, the legend of zelda :Tri Force Heros, new super mario bros 2 ,super smash bros for the 3ds and many more.
