Why Brink for PC failed?
Easy to answer:
The only good thing about Brink is the setting or let’s say the idea with the Ark in my opinion. Everything else failed hard. It motivates maybe some ex-CoD players who never experienced a proper game, but the core gamers (mostly ET and ETQW fans) left the game with good reasons.
Brink has nothing to offer except a crappy console beta gameplay. I share this opinion with all those unlucky gamers who bought this fail game and left it disappointed.
SD sold many copies now, because all the core gamers bought it, but I am really interested how they will advertise their next game after Brink
