Hi i'ts probably been asked already but I've played Avernum 1 and 2 and started on 3 (though I'm not sure I should play through 3 since the whole timed quests thing (I hate them with a passion)) anyway I was thinking of just jumping into Avernum 4 but I was wondering should I wait in buying this since there could be a remake of the next three games(if there's going to be a remake) or should I just buy them and say goodbye to weeks of my life playing these like I have on 1 and 2
