I know many adults that play Graal. Although I personally find it a tad odd and can't imagine myself even doing the occasional visit to these forums in the near future, there is a minority that have been around for over a decade and that's fine, they're generally good people from what I've seen.
However, the adults that play Graal, then proceed to whinge about maturity levels and the community whilst believing they are superior because they've been playing a 2D virtual game for years should take a good hard look at themselves though. Bear in mind the new iGraal demographic is aimed at 10-15 year olds with credit cards...
