40K is certainly not rubbish, just a game set in a different enviorment and in a different scale of forces. And with the new set of rules, it is really splendid! Better than Warhammer fantasy in some respects.
But if you do not like to shoot at things, dislike automatic weapons and modern urban combat, hell yeah, call it what you want, Notts.
If warhammer became more objectivebased, who knows what wonders could be worked?
