Ah - Fast Travel. We all love it. Or not...
Fast Travel - IMHO - destroyed - games. Players are encouraged to fast travel, so they run to some target exactly once, and from this point on the never again use the ways, they always fast travel. This way they can solve quests in record time and the game ends after only 40 hours or so. ALso, since they only ran once towards a place, they do never see 70 or 80% of the game world, just one way, and then it is fast travel. Travel systems, lovingly implemented, are ignored. And therefore no longer built into games. Quests are written with fast travel in mind, which lowers the general quality of quests. 'Fetch'-, 'Bring'-, and 'Go Kill'-Quests are now standard, all to be done with fast travel.
Play Bethesdas games: In Morrowind they had implemented a series of travel systems, and they were fun. But people complained. Now they have fast travel. Wit all the consequences.
So I do definitely not want anything like fast travel in ED. But this is IMHO...
