A very niche game that isn't about maxing things out. It's all about playing it for the long run, not for 'finishing'.
The customization seems huge at first, and for all arguments, it is rather large. It does seem to be lacking in some spots though despite the variety. For clothing, most of the clothes (especially on the Security side) stick to blues, greens, and grey to white camoflague patterns. A little variety may have helped. As far as gun customization goes, skin mods would have been a welcome addition and more attatchments may have been nice, or at least more challenges to unlock the different weapons.
Overall, Brink is an enjoyable game, but feels slightly unfinished. Brink strived to do a lot, and did ok, but wasn't able to excell in any one catagory. Definately rent before buy, but do not miss this game.
