depends entirely on how they change the game. if from prerelease footage i can already tell its mostly changes i like, i'll prolly end up buying it day 1. if its harder to tell if i'll like it, i might end up waiting a few weeks or months to watch others play the game and have some bug fixes get pushed out before making my decision. as much as i adore playing civ6, theres a part of me thats worried that after all the time i put into civ6's systems, it'll just be frustrating to switch to a different game. tho i'll always have civ6 to keep playing, so who knows
anyways very much doubt i'd preorder. i dont really care what reviewers have to say, i care how fun the game looks like itll be for me, and i'd wanna be really certain of that before i commit to spending money on the game
