Well, This was the idea I had for my submission to the Christmas in July contest. However; the filesize was 1.14MB and a few days before the contest deadline I realized there was a filesize rule, and didn't have time to fix the filesize. Anywhere heres the basic Idea of the game if anyone likes it feel free to use it, cause I'm not going to anymore.
Gameplay:
The basic Idea of the game was to Steal "Presents" (Psi Emitters) from the other players. You start out with four presents and a "Head Elf" (Probe). The game begins like a normal Cat & Mouse game. The "Head Elf" goes to find minerals and create a "Storage Center" (Nexus) and collects "Christmas Spirit" (Minerals). With Christmas Spirit you could buy units and special abilities. The overall objective of the map was to get to the other players "Christmas Tree" (Beacon) and steal the presents out from under it to keep as their own. Each player could hold up to six presents. However, you can also cash in presents at the "Present Exchange Booth" (Machine Shop) for minerals if you already have six presents or if your just desperate for cash.
Anyway if you like this idea and would like to use it go ahead. If you want the unfinished version of my map, ask for it and I'll PM it to you. You can edit and change it all you like.
Heres a screenshot of the minimap for the version I created.
