I think Fizzer should allow people who haven't bought membership to make 24 player matches only for Single Player, what do you guys think?

I may be wrong, but I thought you could utilise member settings on single-player.

i dont even remember anymore since im a member

You can use Custom scenario in Single player, which is a member only in multiplayer (I believe, didn\t check :p) However you can`t invite more than 6 players (AIs)-I checked that

Custom scenario is a member-only feature. Thanks for checking Hennes.

custom scenario can non-members also in single player but with a max of 6 players and I would also see happen that it can be highered up

can't you create multiplayer game with only one player(you) and 23 AI ?

That would be single player^^^, and no, you can't according to Hennns.
