not OP. When I think of most technologically advanced games ever, I think of graphics and technical difficulty at the time, not the size of the "explorable" map. WoW has massive maps but graphically and in technical requirements takes very little to run well. EVE is massive as well and has built massive scope with most people who trade needinh to master excel to keep track of what is profitable at what time of day. EVE's technical aspect is limited as well mostly due to age and the want to run on more systems (just like WOW). It is common for players to run multiple instances of EVE to control multiple alts.

Star Citizen now is probably closest to Crysis. In that the game engine was so complex running it on ultra settings with the best of current hardware would have resulted in an unplayable framerate. Star Citizen's approach on it's physics engine is substantial both space flight and first person shooter aspects. ship physics note, newtonian flight physics. I have been watching a few of their "in the Verse" and other videos recently, and it is interesting (though the presentation can be pretty dry in the videos).

Seems I am making this too long. Just a quick(lol) thing about the character models, they worked a lot on getting 1st person view to be accurate using camera stabilization techniques to smooth out the view like are brains do automatically while running, your gun shoots where it is actually pointing and not from the center of the screen, what you see your character model is exactly what other characters will see (keeps you from wondering how you were "shot through a wall" when you could tell you were completely hidden where in other games other players are seeing a different character model).

Building on those ideas we wrote a system that takes snapshots of the player’s requested movement and determines if the player is making a large enough change that would require extra steps to slow down or change direction. This comes in the form of starts (idle to moving), stops (moving to idle) and jukes (quickly changing directions). .... So we’re sorry to say but we won’t be supporting 180 no-scoping or strafe-jumping.

Star Citizen's FPS module is very similar to ARMA 3's in terms of technical aspects.
