Personally if space legs = first person shooter then I’d say this is very wrong. Elite is about many other things, and not pew pew gameplay. You don’t invest hours of developing your commander and his ships and wealth, only for him to be shooted by some FPS person somewhere randomly.
If space legs = walking around a controlled spaceport environment in a station with other characters, seeking out that elusive contact who has that illegal star chart you want to trade for credits, all whilst eluding the security team,admiring the view out of the window of a seedy space pub, then ok perhaps I could get on board.the gameplay mechanic of security, pirates, trading, etc should be carried over and reinforced by personal interaction.
One thing space legs should do is reinforce the scale of the ships and the spaces. Walking around the hangar would be awesome.
But to me, Elite is primarily about ships. Spacelegs could break this fundamental of the core gameplay if not handled extremely well.
But I’ve played elite ever since the original bbc version so perhaps I’m biased!
