the exiling once every 24 hours is just retarded indeed.
just don't do it
I like 2 BP's per gal of 2/3 people. This will yield
- a struggle for power within a galaxy, which only makes people more involved in the meta game which can only be good
- a lot of mixed galaxies where there will be a 'civil' war where people will dislike/like eachother a lot. Maybe some changing on who can see what fleets might be cool. (that you only see fleets of planets that put themselves or others on 'not trusted' if they are flying for 2 or more ticks and then see the original eta (or not))
Thinking of this maybe even 3 bp's of 3 and then 4 randoms without exiling. This will I think lift the level up from the bottom up, instead of making 'the best' better.
However one more suggestion, which could be made in a better way. But this is it:
Do not, ever, let gm, have a say in anything. He simply does not understand or want to understand the gamemechanics and the meta game.
