I would like to be different and vote for a new map...but a new Creative map.
- biomes aren't finished yet (no snow right now, for example), and this will affect terrain generation (including in the nether)
- no NPCs in villages yet, so they're less exciting to find right now
- more strongholds with bosses will be added
All of these things are gonna make us want another new map when 1.9 comes out (within 2 months, possibly 1 month depending on if there is going to be another version before the "full release" version) the same way we had no snow, no new trees, no lapis lazuli anywhere nearby in the current map because they were only generated in the new sections of map.
With a creative map, we can freely test some of the newer features (like minecarts/rails, pistons, etc) without having to mine forever to get enough iron, gold, etc to make them. Terrain generation won't matter as much since the new blocks will be free anyway. We can build stuff quickly, rather than spending the next month building up inventories of building materials only to start over again if we want to make a new map again at that point. We haven't had a good creative map going since almost a year ago.
What does anyone else think about that?
