All right, I am in the Space Phase now, so I figured it'd be great to do a quick review of the game, and I may go in-depth later.
First off, the game cannot be viewed as one product and get a score it truly deserves. Instead, I am breaking each phase as it's on separate part of the game with my opinions on it. I use grades, btw.
Cell Phase - B - Now, when Spore was announced, I couldn't care less about this phase. It just looked boring and shallow. Once I played it, it's actually pretty fun and deep. My one problem is that the phase is ridiculously short. I'd love to keep advancing to those massive creatures you see under you at the top level. This part REALLY surprised me.
Creature Phase - B - Like the above, I wasn't looking forward to the Creature Phase at all. It just seemed boring to really, and honestly, I'm glad I was wrong. The creature phase has so much to do, explore, and customize.
Tribal Phase - A - I thought this stage was actually a lot of fun, albeit a bit easy. I did have trouble impressing other villages with music, but I think that was just frustration. Pretty fun overall.
Civilization Phase - A - I LOVE RTS games. This mode felt just like Savage's RTS element - simple, but still fun. You can only make really basic troops, but there is a lot of strategy to actually taking cities. The military route is pretty hard, but the aircrafts aren't very good.
Space Phase - D - This is literally the best part of any game ever. There is still so much you can do. When I got out of my solar system, I realized there are stars EVERYWHERE - above, below, left and right of you - all with at least one planet, which either has life or can hold a colony. Then if you look at all the possible tools you can get, it's even bigger than I'd have ever imagined. Well, it was an A+, but then I really started playing it. This game fails where all other Will Wright games fail - overwhelming the gamer. Look, I get that you want to make a challenging game, but I can literally go to no other stars now. As soon as I touch a star, which are all hostile now, I am told to go back home and defend against an alien invasion. It's cool, once, maybe twice, but when I am looking for friendlies and cannot make it that far, then it's ******** and annoying. Another thing, the enemy ships are entirely too powerful. Their rapid-fire lasers destroy my armor while my missiles slowly takes them down. This really shows that under it all, the game still has work to be done, which sucks.
Overall: B. Solid game, that I really think expansions will make better and better.
