Both Rainbow and GRAW2 offered significant choices of generic heads (sometimes both male and female), headgear and eyewear , generic paint options... adding custom paint does not seem to add much more to the mix. It also doesn't add - IMO - anything to gameplay since the amount of time you spend actually looking at other faces is minimal.
I truly hope that the ability to add custom paint is not what sets GB apart in the realm of MP FPS.
Putting your face, and player customization might not mean much to online multiplayer....but to CO-OP with your actual friends.....its the best thing since sliced bread.
To this day we still play the game that "WE" are in.
Nothing is better than actually seeing your best friends face IN GAME for that immersion feel.
I can see how playing ONLINE with people you have never meant would just be a hassle....but a small group over a local lan playing CO-OP....FANTASTIC....and I am praying that it makes it into more games in the future...so my clan can move on from OGR.
