... Despite some of the obvious flaws, it shows that Splash Damage definitely has the ability to make a future game that could easily become AAA. They just have to get ignore the negative reviews, listen to there fans, and work hard on the next game...
You do know that Splash Damage are not new to the scene right? And that Brink _is_ a AAA title already?

SD's games have always been awesome (IMO) and Quake Wars was a full AAA title too. This is just SD's first game with their own IP and I like what they've done.
TBH the only issue Splash damage has really had with this release has been with the consoles. This (I think) is the part that they need to learn the most from and will hopefully, in the future, be releasing more smoothly across multiple platforms.
The only arguments against calling Brink AAA basically boil down to AAA being a marketing term with a very vague definition.
