Great fun, not quite what I expected.
This game reminds me somewhat of MySims, it's quite interactive and involves a lot of "back and forth" tasks. Some of the conversation options/questions seem redundant, and unless you're on a specific task you can waste a lot of time talking to guests.
I'm not a massive fan of minigames and there are loads in this game, some of which you have to complete (well) to advance in the level - infuriating for me!
I've been enjoying designing the rollercoasters, and the step by step instructions are pretty easy to follow.
I've almost completed it now, and I've put in less than 20 hours gameplay so far, so it's not a long/difficult game to complete.
I have noticed a bit of a lag when running through the tunnels from one area of the park to another, but that's about all.
