A personal note on Super-Stacks:
I have played my fair share of games and I have encountered large stacks from not-so-good players, but I have NEVER encountered anything like a super-stack. The only time I was baffled by the sheer number of units in the enemy's hands, was when playing vs someone with a gazillion planes, but... this is such a good player, that there is no doubt that he built them himself. And since my industry was not the smallest itself, I countered correctly with a gazillion of the right units....which I built myself.
So, if any super-stacks were observed in that game, they were hand-made by the owners themselves.
Now that Super-stacks are being considered such a severe problem that unit trading must be BANNED, the logical solution then is:
---> LIMIT INDUSTRY DEVELOPMENT!! As soon as a player worked hard enough to get to the nr. 1 to 3 position in industrial capacity, the TOP 3 of every map should be blocked for a week from building more industry, so the rest can catch up....
For the ultimate solution, Devs should combine this measure with one that I mentioned in connection with 'the market being perceived as so powerful that it should not have so much influence'. Remember that one? No?
Well, I suggested that actually not the market is so powerful, but players are and that thus the number of players should be limited to 1, so that everyone can be a winner!
Now... with 1 player on the map, combined with limited industry development, truly no-one can loose a map, because even AI will be restricted from outdoing lesser players by industry capacity.
So....once having implemented these changes, the chance of anyone complaining will be reduced to zero...ALMOST. I say almost, because some players will still lose due to themselves.
To avoid any further complaints by players, the Devs only need implement 1 more step !!
The 1 player on the map should no longer choose a country to play and then run that country! No, the way to go would be that the 1 human player per map choses a country and immediately AI takes over!
All issues solved!
