I've been working around with this engine for a while. Before you just got a 30 day trail- but now with the 2.6 update they are structuring to where you get Unity 2.6 free for personal or comercial games.
Where they hope to hook you is on added features that they will charge for- like an asset server (so team members can work together) and other higher end features like post processing support- etc
http://unity3d.com/ To look at the comparison chart go here:
https://store.unity3d.com/shop/ and
http://unity3d.com/unity/licenses As you can see- if you want iphone support it's 399.99 and so on.
aside from that comparing unity to the pro licience your not getting some things like Realtime shadows and other fancy things that the average independant likely doesn't use anyhow- and just about anything on the list has a work around (browse the forums).
This is a great deal. If you've been on the fence and want to give it a try there's no better time than now.
How's it look? It's all about textures and lighting- but if your interested in web based games unity is pretty good. It can handle most things though i'm not sure i'd do a flight sim in it.
Here's a pretty nice screen I found from a game called 'Global conflict palistine' I found on the forums.
For comparison here's a screen from the engine being used for MJ-12 (A7)---those player models look like crap as they are only placeholders.
I'm sure you could get simular results in Unity if you worked at it a bit.
Also I located a Unity Dialouge Editor that plugs into the engine- this would be great for RPG's, adventures and FPS games.

http://bionicle.lego.com/en-us/games/glatorianarena.aspx Robot fighting. It's pretty good.
So download it- try some tutorials and have at it. It's pretty easy to learn.
