Battleships forever is hardly more than a toy
Graphically horrible but aside that also doesn't simulate diminishing armor piercing, stacked armor, different armor types, deflection ability, heat absorption etc. multi-layer shields, crews, energy links, reactor efficiency or compartments.. etc.
If you make a tactical space battle game it ought to be realistic - even if the numbers are science fiction CONCEPTS of physics should always apply - The reason i am writing that is because i still haven't found a Silent Hunter 4 in Space kind of game, i want a capital ship battle sim - IN SPACE
The only game that has an barely realistic combat system is, weirdly enough - Space Empires IV
Imo these games need to move into the hard-core segment and stop being arcade - GSB is the best example, albeit fun its ultimately extremely basic - the underlying gameplay concepts are simplified to cater to laptop/casual gamers - what i talk is a hardcore game, like AI War is hardcore RTS i want a Hardcore GSB kind of game.
