Haha, yes, Windsor Davies - 'up the jungle' :-))
Anyway - back to the topic - I'm not familiar with those games. How many figures would you expect to table in an average game, and is it squad based or skirmish type as that often dictates figure scale - fewer figs, larger scale seems to be a rule-of-thumb.
Pretty much my only experience with SciFi figure games is 40K, 40K Epic and GW stuff in general.
