Original war is an RPGRTS game that truly original, yet till now no other developer trying to copycat its features to their titles.

If you are not graphics fanatic, this game will let you:

-Travel to prehistoric time, meets flora and fauna that exist 2 million yrs ago
-Let you learn prehistoric apemen language, and persuade them to join in your ranks.
-If you already persuade the apemen, you can "train" them as you like, from being mere construction worker, rifle-apemen, to suicide bomber, whether walking or in-vehicle!
-Modular vehicle construction. That is, you can change its weapon / civil tool, engine, chassis, and operator as you need. Not many RTS offer this (the other game I know is Warzone 2100).
-Exotic armament, from soporific ammo to localized time-slower device and teleporter rocket.
-Question you the morality, ethics, and even soviet history
-Such question above will affect your in-game fate. Seriously.
-Your previously placed building will be brought to next mission, so carefully place them

And the most important is:
-Let you treasure your minion, train and supervise them (just like in real life!) because they are the most irreplacable resources in the game. Even you will missed some funny comments if they already dead before.

And all of that feature is existed in 2001 game.
