I did enjoy the adventure games at the time, but not enough to wish for a third, I actually thought heroes was as good (almost certainly in a minority there).
At this point I'd just like a somewhat enjoyable 3D entry, I've only fully enjoyed Generations but found bits to love in nearly all other 3D entries. Unfortunately games like Sonic 06, Sonic and the Black Knight, Sonic Boom and Forces have killed my instinct to auto-buy mainline Sonic games.
As for a collection with the Advanced games? Yes please, they are somewhat overlooked along with Rush!
