<insert question on how would one balance this since he can't imagine the Fire Nation squaring up against the Imperium of Man and that jazz>
[/quote]Oh well, I didn't want to make a double post but without that you wouldn't get the alert so whatever.

Well, first off this game wouldn't be as competitive as it sounds, it's mostly about small portion of a faction being stuck in a new world. ISOT is a term often used for these. Writing a fun story and developing your new nation will be more important than power playing.

Second, more powerful factions will be arriving with less men. Or at least will be allowed to. You can nerf yourself voluntarily if you want. No need to stick with set numbers here.

Third, power levels will be capped up a bit. Familiar with "VS debates" I suppose? Calculations and analysis can help at times but here we'll ignore most of them for the sake of fun play. There are many techs which are far more OP than you'd think as well as many massively superhuman characters who make anything else pointlessly inadequate in comparison. These things will be toned down. For example beam weapons from Gundam/Code Geass and any other mech series won't have kilotons of yield per shot even though they do have such showings. Instead they'll be treated as "better than guns at dealing with enemy armor". Walking WMD type units will be rare and high-tier. So are the actual WMDs like nukes. Superhuman characters will be toned down to the level necessary for the plot and they'll be accordingly rare. Granted, these won't be enough for example to prevent W40K IoM wrecking forces from Ancient Rome but that's not the point. Also in this game if somebody plays his/her cards right can quickly develop into a more advanced nation.
