Well, the beta will just not be a complete game. Dwarf Fortress isn't either. The start is fun, but the later game stages get boring. As for Elemental, it's called "War of Magic" but Beta 1 won't even have magic.
So yeah, you're playing an (majorly) incomplete, buggy game with simple graphics. It might just be that some people don't find that fun.
However if you do, more power to you
