Am I the only one? I would really like to start a new game of X4 now - but with the upcoming update I am not sure the saves will be compatible - So I wait for split vendetta ... but ... but - 1st world problems, I know
By the way Ego - I really enjoy X4 so far - but a bit more Info would be appreciated - maybe a screenshot of the day revival?
To my knowledge, there has never been a situation where save games are not forward compatible within an X Universe title (X3:R, X3TC, X3AP were different titles) outside of betas so you should be safe.
I hate having to start all over again within a similar universe (e.g. X3TC to X3AP) so end up using exploits to get up and running again quickly and reap the rewards of an expanded universe and improved gameplay but I don't expect to have to do that for a long while. The way Egosoft have operated to date is for each new version of the same title to add significant content and improvements, although, content comes in the form of DLC these days and this is a good thing IMO as it extends the life of a title far beyond adding some new missions etc.
