Heres a bit of histroy for ya...
So the Final Fantasy Series (FF7... I mean who didn't have a tear in their eye when Ariel died?!?!) were good - but just to go even older...
My favorite old arcade game was "Rampart" - with Tetris style blocks you had to build a castle wall, in 20 seconds (and getting pieces to fit on a small piece of land is no easy feat) - then you got to place cannons (taking up room of course) in the walls, then for 30 seconds you would shoot at ships attacking from the coast. They of course would "pin" single holes in your walls - so the next 20 seconds for repairs getting tetris pieces to fit in damaged areas was very tricky, and because you had cannons (which you wanted more of but they also take up room) they also got in the way of you "tetris repairs"...
The nice part about the NES version later - was the campaign style mission.... playing on HUGE maps (several screens wide) where 30-40 enemy ships (some firing explosives, some with fire... landing parties blocking hole repairs) would attempt to block you.
Good times...
