In real-time?
Jump-gates for near instant travel between systems and warp tunnelling withing systems exist in games for a very good reason: space is big. Really big. And even light is slow by comparison. Players get bored easily.
That “feels a bit slow 3AU/sec” is still 1,500 times the speed of light.
(Warp factor 9 for all the Star Trek enthusiasts out there)
There are good playability reasons for not doing it - it would be like having a real time sailing simulator where every journey is “cross the Atlantic in real time” but without the excitement of waves and changing wind direction - solar sailing isn’t as exciting as wind sailing at sea, everything is constant and predictable and really low forces.
So saying, I really like the solar sailing concept as a way of exploring the inner solar system - it just wouldn’t work in s game like Eve.
