OT-Some New games

[Phoenix-D]

"Kinda OT for OT, but does anyone remember an old Amiga game that was based on a turn based/top down view BattleTech game?"

Mechforce?

On the same idea: Megamek. A BT port to the computer- and unlike all the other BT ports out there, this one actually got to the playable stage! BT, not Dark Age. Thankfully.

Also Titans of Steel. Said it was based on the game you mentioned above..it's essentially a clone of BT with some different elements. It is also NOT turnbased, but not real time either.

You give your orders, which take a certain amount of time. When a unit finishes an order, you can give it another one. Meanwhile every other unit is doing the same thing; the overall effect is like real time, but without the stress. Nothing moves while you give an order, no time passes. Long periods where units are doing nothing are just skipped over instantly, and you zoom ahead to the next order.
