I've been playing an inordinate amount of Brink recently - so please take my word for this. Regardless of what you think you've heard about Brink, you need to be aware that £9.98 is an exceptional price for it. Tight teamwork and a monstrously addictive upgrade system overshadow and trivialise its faults (and mechanical gripes), and any misgivings about the eight arenas melt away at this price point. Plus, they fixed the lag.
Free DLC, updates and clan support are incoming. Let's hope that there's still a thriving community left when it hits.
