I was actually just talking to a friend about this just a few days ago. My friend and I found an amazingly great group of guys who are family and friends who consistently play with each other and in a family-friendly environment even (regarding language). Now for me, it wasn't a big deal to adjust despite i can could put a sailor to shame when it comes to rage-swearing lol. Any way my point is that in this group, there was 1 kid, maybe 2, present that night and they were able to hold their own during our 33 crota run. Everyone got along, communicated what they needed to, and no complaints were made. Seeing as how this is a video game, a social one at that, age SHOULDN'T be a factor so long as they can pull their weight. I realize this could easily fall under 'a perfect world' scenario for some or many and maybe I just got lucky with being invited to play with these guys, but in the end the game is about teamwork and cooperation, not discrimination.
