Thats fine, everyone has their poison. I personally dislike games purely based on graphics and "open-world environments" because they never fit my expectations.
When I hear open world, I want OPEN world, not a "big box" with largely undetailed environments and generic gameplay.
Spore will be perfect then because you can travel across the entire "worlds" in the game
too bad the planets look like they are no bigger then a super walmart.
