Well, why bite the bullet and buy something that you know isn't finished and will take months to complete, when you could just buy great games now and buy Elemental later when it's something worth buying?
The only problem with CIV 5 is it will just be another Civ, the video doesn't make it look appealing to me.
No even in it's somewhat poor current state I'd rather play Elemental.
You do realize that Elemental is just another civ too? Start with nothing, build an empire, win by diplo, conquest, science, etc - sound familiar? It's civ, or the basic 4X formula, just a different wrapper, and in the case of Elemental, it's a ripped up, broken, incomplete, and simplistic wrapper.
Elemental is supposed to be a spritual successor to MoM, or at least be similar to it. Does that mean Elemental is "just another Mom" and not appealing? Err, guess not.
IMO, every element of Elemental is simplistic - there isn't one thing about it that is compelling. Mostly human units/leaders in a fantasy game. Simplisitc units. Simplistic magic and spell system. Simplistic city/empire building. Poor UI. Poor in-game info. Poor AI. Poor tactical. And so on. It's hard to find one thing about Elemental that really grabs you. The game does oddly have a "one more turn" vibe even with it being a shell of a game, and you know SD will bust a move and improve, but it's just not the game it should be yet and you can only hope that some day it gets there.
I love Stardock. I consider GalCiv2 (to be SD's best game, Elemental is nowhere close, not by a longshot, sorry Brad) to be on par with Civ IV, and Civ IV is one of the best 4X of all time. Elemental is nowhere near the quality level or gameplay level of Civ IV or GalCiv2. Not even close. Maybe some day. Why play a prototype til some day? The state of Elemental is nobody's fault but SD's - it didn't have to be like this. Civ 5 will instantly be at or beyond the Civ IV/GC2 level upon release.
Why play a prototype and a shell of a game when you could play what will be one of the best 4X games ever now, and come back to Elemental when/if it reaches the potential and state we all hoped it'd be in and hope it some day reaches?
I could just as easily be raving about Elemental if it was worthy of such praise.
