so I've been adding Elite(exp) to one of my stations, now I realised that there is another Elite mode (missing the exp which i assume means that its non experimental).
So... which ones the latest?
can I replace one with another?
does it even matter which of both I'm playing?
whats the deal with the stations anyway?
why would I need to buy more stations in order to be able to play all modes?

elite exp is an experimental version of normal elite (you don't say), in which nadeo is testing some features, which might be later added to the Storm, like walljumps, laser jumps etc. (full list here). you can play the one you like more, they're fully separate, tho at the release elite exp will probably disappear, since all its features are going to be included in the normal elite.

Alright, thx for the reply

Space says...

since all its features are going to be included in the normal elite.

or not, lets wait and see
