I'd just like to request that on maps with rare resources, there be at least 1 instance of elerium somewhere in the galaxy.
My preferred settings are insane with rare resources, and with those settings I've yet to see elerium, even 1 instance, on any map. Which of course limits my Hyperion Shrinker capacity by 10%.
edit: which makes me cry in the late hours of the night.
Also, maybe randomize per game which resources are required for the various weapon special enhancements. Or even per game and per race (so its individualized to each race, including the player, which resource is required for each enhancer, changing from game to game).
