I don't even understand why there is a discussion. The Morrowind-stye fans have already budged and said that it'd be okay for them if
both systems are in the game at the same time (at least, that's what I got out of several threads here).
There is no drawback for the Oblivion-style fans in this. Because in THAT case, you can actually aplly the notion "Don't like it, don't use it". Because there is an alternative, and you never need bother with the horrible, horrible travel routes idea.
(For Morrowind-style fans however, there is a drawback - no matter how much you love one system, you will always be tempted to use the easier one if it's available. But that is at least a minor problem in comparison to not having their preferred transportation system at all.)
Other noteworthy points:
- Morrowind's system definitely made the world nicer to look at. Even if you didn't like silt striders, they were one of the strongest impressions of the game, and helped define the land's alien nature. Not to mention all the small villages that had a dock simply so that they could provide travel services, or the one extra NPC in his nice teleportation chamber that made the Mages Guild guildhalls a little less empty. If I'm not mistaken, there is no non-stupid argument against this part of the system.
- It literally takes less than ten minutes to implement Oblivion's fast-travel system and make it bug-free. So "both is too much effort" just doesn't work.
- Even if all MW-style fans played on the computer, it still wouldn't be as easy as "simply install a mod that does that" for them. Why? Because it's not a very easy mod to make:
1) Voice acting is a major problem. 2) Missing meshes are a major problem. 3) Missing travel menus are an almost unsolvable problem. 4) Compatibility with other mods is a problem because you'll have to make major changes to every featured town.
The result is that the
first mod that came even close to Morrowind's travel system for Oblivion was released in 2010, six and a half years after the release of Oblivion. (It's one of my mods. And apparently, it's buggy as hell.) All other transportation networks simply connected the 8 big cities and disabled fast-travel, which is not what MW's travel system is about.
BTW, in response to the poll: I hate the idea of earning a gameplay feature by completing an epic quest. It just doesn't work for me. After a couple of playthroughs, the epic quest will be an epic nuisance. But also, it mostly feels fake, especially if there's a message like "You've slain the evil lich that blocked the teleportation system! From now on, you can use teleportation." (or whatever), it's a big immersion-breaker for me.
Certain spells that allow you to teleport to anywhere you want... I would like that if it was really integrated into the game, so that NPCs will actually give you x, y and z coordinates of some sort, or mental images of the area. I mean you'd have to know where you're going somehow, and seeing the effects of such magic on a society (invitations to parties with teleportation coordinates written on them etc.) would be cool (though not exactly what I expect from TES).
tl;dr: I voted for Morrowind's system.
