However, I feel as it stands now the game will be too difficult for any side to win in a reasonable amount of time, and thus am looking at implementing more snowball mechanisms. In addition to that, as with any free for all style game, putting in place some anti-turtling mechanisms is probably going to be helpful.
If anyone has general ideas for snowball, or anti-turlting mechanisms / design techniques please chime in! Here are some possibilities:
* higher resource income based on teams' map control, leading to better equipment and teleportation ease (currently the only one in my game)
* experience; leveling up with new abilities or better stats unlocked based on time and distance spent away from your homeworld
* buffs (eg Baron buff in LoL; a team doing well enough can secure the powerful Baron further increasing their advantage)
* stronger NPC allies / weaker NPC enemies based on map control objectives; (eg destroying an Inhibitor in LoL gives your team more powerful minions trying to defeat the enemgy team)
