Its not nearly as free, no, and yes its templated.
The problem with Minecraft is that its freedom is a double edged sword.
I'd much rather have templates and limitations, but be able to delineate an area within which nothing can spawn, so that defenses and construction matters more.
That's a personal preference thing though. I don't expect anyone else to agree with that opinion, and that's all it is. Just an opinion/preference.
The reason I don't play Minecraft at all anymore is because the one thing I want to be able to do, which is construct settlements and fortifications and traps and see how well they repel attackers, I simply cannot do. That was the strength of dwarf fortress that Minecraft has always failed to replicate, that I desperately seek and desire in other games.
