Curious question: Does a GM release exist anymore? I mean sure you, some other kind of devs and publisher care about a (most) bug free, finished version, before they release is it.
But usually it looks for me as buy it on the release date and you can put it in the locker and wait. Either the game will mature over time or it will catch some mold. Sometimes the mold is so thick that the publisher abandon it or even take it to next garbage dump
. Perhaps sometimes they even will charge you for a the "patch" of the "beta" you have brought, so that you can have a "full" game.
And I do not mean the DLC (
disc
look
content not the
down
loadable
content) on day 1 releases games or the never ending catalog of warderobe items that you can buy for your preferred character.
Down
loadable
content on day can have their reason, but
disc
look
content means for me that they have enough time to have it on the mastered disc itself, so this is only a sales decision.
