Fristly, I want to thank relic for DOW2, it is a wonderful game. So good that I would not hesitate to buy DOW4 if relic is up for it.
DOW3 had alot going for it outside of core gameplay. Graphics, sound, cinematics, models, were all 8s or 9s. I think Relic rage quit on DOW 3 too early. If it was not for the recent example set by Rainbow 6 seige I would have thought otherwise.
Relic probably had other options, other games to put their effort into. I am sure if Relic's back was against the wall that they could grind out a victory with DOW3.
In anycase, Relic has my full support in whatever they do. Making games is the most ballsout batnuts industry I can think of, it must be incredible stressful.
