Wouls they be happy with the Demo Version, though, as an example of what to expect from the full feature expected for release at some point in the future. I really have to be honest, anybody who settles their heart on a single engine code, just because "it is something they have used before" and who generally cannot be assholed to try a game on an alternate engine OBVIOUSLY have no sense of what it may take to build a serious game with the possibility of keeping constant interest.
Fact is, although I have kept on saying that I do not know what BYOND can do etc etc, all I'm getting from you is constant BYOND BYOND BYOND. From what I know, BYOND is a basic and quite simple engine to use without the possibility of furtherance, whereas, Eclipse and Mirage consist of a higher quantity of option.
It has, however, already been decided on what engine is used. This game is not here to suit yourself and your friends, it is here to adhere to anyone who wishes to join the community and play the game for what it is. Your friends dont like it? We dont want them.
