… and have been having a great amount of fun with it since I got the 30 day free trial. Here is a finished product (scene) I worked on since I started (with the help of a few free asset packs from the forums XD) . ( I love this editor! XD ) But the price is really… really steep for me. =p Just thought I’d post this and show off something I made within a couple hours of knowing about Unity. Thanks everyone at Unity3D.
There is a free version of unity available. Unless you absolutely require some of the Pro features.

Yeah, I saw the free version… I got that first. Then when I went to try and render shadows, it told me that it required the pro version. I feel that without shadows in this day and age of video games, it makes the game seem very plain and simple. But that is just me =p I’ll enjoy the 30 days while it’s around, haha. =p
You can have blob shadows in the free version
NAKar think of the whole thing you can have for free.
No shadows but you can do A LOT with it.
And then, if your product will deserve shadows, you’ll buy the pro version 
BTW compliments for the scene, it is really cool if you know Unity only since some hours!
Also check out the Beast lightmapping: in the free version it is limited to occlusion and shadows, but still very useful!
