look at the rankings
the only non tauri or asgard in the top 10 is one player who is a goa'uld in 9th.
the highest ranked replicator is only 11th.
if assimulation isn't introduced, reduce the cost of spies or something simple like that!!!
assimulation should be a VERY small percentage, and small weapons could be used to counteract this but naq (or men as somone suggested) could be won as a result
i rekon this is a good idea and there should be a limit on amounts of units assimulated e.g. 5 big weapons a day (only about 850k naq).
and it should be an extention to covert (it uses covert turns)
