what happened to this thread lol
overwatch is a great game though, feels very refreshing when compared to the majority of new titles lately. no pay to win, doesn't rely on gimmicks, good presentation, solid balance at a pro level as well as the nooby level. hopefully blizzard doesnt ruin it :~)
unfortunately I can't see tf2 hold a competitive scene whatsoever with the existence of overwatch, as overwatch is expected to have more attention from the devs, a larger playerbase, bigger prize pools, as well as simply more interesting gameplay (sorry tf2 players)
until blizzard allows the community to make mods or host servers though (lets be honest this wont happen) I can't see overwatch taking over tf2s niche - community servers. xG will be fine, tf2 will be fine, just those 500 comp players and valves new matchmaking probably won't be.
