I taught myself long ago not to have high expectations of games - in fact my expectations lower in direct proportion to the amount of hype a game or sim receives before its release (same goes for TV shows & movies).
Examples:
GPL: out of distribution by the time my mate showed it to me - now it's my favourite racing game. Ever.
LFS: never heard of it before some GPL'ing friends told me about it - played it, loved it right away.
GTR & rFactor: comparatively big hype - disappointing
GTL: my PC can't even run the demo but damn I'd love to give it a go
nKP: not much hype but I'd played the namie lots and lots and loved it. A few bugs and some glaring PR issues (which was disappointing) but plays wickedly.
iRacing: again, not much hype apart from the occasional email update (hence this thread) but GPL's Dave Kaemmer is on board, so I'm cautiously optimistic. The iRacing guys seem like a pro outfit, appear dead serious about what they're doing and provide updates when something relevant occurs. Hype-o-meter isn't registering that much, so I reckon it'll turn out ok
