Great Game, but Needs Some Fixes
This game is very good, and could be outstanding with just a few fixes. As mentioned in other reviews, it's very long and can be ended be sheer bad luck at any point. There are two possible workarounds for this:
1. Add a save feature. This one should go in no matter what.
2. Add an upgrade to deflect incoming projectiles, that can potentially save you from an unblockable death assault. Make it, say, a Phalanx CAWS type system that can't reach enemy tanks but can shoot down their projectiles. Give it a charger like the shield, enough to only take down say three or four shots without spending fifteen seconds or so to recharge, and voila! You have a fun fix for the problem that adds to the already impressive strategic options of the game.
