I mean, I am waiting for the game, but there is no denying that:
A: the EGO engine is reaching the absolute limit of what it can do, and even if it wasn't the case, the EGO engine has been long in the tooth for years and they desperately need to run with something new. Maybe getting Evolution into the fold would have helped, but lets just murder the studio for reasons *shrug*
And maybe most importantly, B: Codemasters has always had massive problems with post launch content, and in a world where such things are considered common place, it really doesn't show much confidence that Codemasters' mantra for the DiRT games is simply to **** it out into the world, make a single patch for 90 days, and ignore it until they invariably announce yet another game. Doesn't help that the vast majority of the vehicles that have been in the DiRT games have been in some form or another, used since the original DiRT nearly a decade ago.
DLC, if used correctly, can give people reason to pick up a game that they otherwise shelved. Codemasters does not seem to think that, and it's killing their ability to have casual players, and hell, maybe even a few sim racers, care about the game longer then maybe the 30 days or so they'll play it. This has been a worrying pattern going back to the original DiRT, and it makes me wonder when people are just going to be fed up with it and stop giving Codemasters the benefit of the doubt. I'm already very close to.
