Yeah it's Unity
To compare you can find some war threads like :
3DGS Vs T Rex Engine
or others !!

Friendly_Frank :
Yeah, it's cheap , but lonewolves no :
caus i'll never sell a game ,not my goal , so 1500$ to have top notch tools to play and have lot of good time ... hummm .. perhaps no

But for serious teams like the ones that maked a game with Unity , yeah indeed,
if you're sure to sell something , it's THE ENGINE

Don't take it bad Albertto

Here are some veteran like in War
So some of us have the reflex to quickly attack before the thread go in
lot of useless directions

It's not 3DGS Vs Unity , but we can say this features exists or not TODAY
in 3DGS ( i say today at this hour , not in some days or in a forecast beat etc ..)

If all people could think by the terms of Today : What are the facts
what have the engine or don't have Today at THIS HOUR.
I think each people would take engine A or engine B directly without waiting future (that sometimes never happen).

That's not comparing that's facts

Well let's stop here and come back to Unity don't want some bad war
, 3DGS is nice engine , not the best perhaps ,but far from the baddest ones

Unity is cheap, if you can affort the price of Maya or 3D Max. I really doubt how many indies or lonewolves have 3D Max.

There is a new demo of unity showing realtime shadowcasting, phyisics, multiple dynamic lights and all in your browser . I hope Im not late with this, but I havent seen it yet.

It looks really stunning, check it out.

The web solution of unity 3d is cool, don't know about its stability though. Installed it, tried a demo and boom! My comp shut down and started rebooting...

I plan to buy a 24" iMac to play Unity, which version of Mac OS you're using?

yes, i also plan to get me such a damn macm only for this unity
maybe such a mini mac will do the job

This is a somewhat silly comment that keeps popping up here... according to you on one hand 3DGS is expensive for what it offers, even though it's actually even cheaper, on the other hand engines like Unity3D 2.0 are too expensive too in your opinion. No one will inevitably sell anything... So... it's never alright. Don't get me wrong, I think Unity3D 2.0 is impressive and all, but it's a bit weird to complain about prices like this...

Cheers
