With current flood of D20, T20 and other games based on 20-sided dice, some might confuse E2O with D20 mechanics. Just a note, E2O is VERY different from D20 system and doesn't need D20. It uses d6's and a random d10 - but if you haven't got d10 at hand, it's no problem.
Playtestings are going on; Today's plan is to try troop assaults, targeting hit locations, recon and reinforcements.
US Stealth battleship and Space station models won't probably make it for this playtesting.
