Gameplay seems 'fun'.
Maps are alright, the two showcased have interesting ideas (three sites, teleporters), but each arena/room seems flat and boring. Also, no level editor or any other sense of community creation. I have a feeling its going to be like Overwatch, instead of the community making mods, maps, skins, etc. , it will be fanart and cosplays. Riot is probably going to run the esports scene too, since leagues can't create their own infrastructure.
Also this thread should probably be renamed VALORANT...
