i don't think this editor is meant to compete with a fps editor. It's a world simulator. You can't put quests or anything there....
Anyway this simulator is amazing haven't seen anything like that in realtime and 3d yet, sand, lava and water behaving like they should....awesome
@Sudi, But Sandbox also has great simulation of world being developed, i.e. the realtime-ness of sandbox wa amazing compared to say UnrealEd:) Though Dust Terrain Editor seem more realtime-ish. :)
I hav ealways liked games that were great core simulatio like fps is generally of shooting in situations(Tactical, Horror) , Sims(life), Aoe(kingdom), etc. Those cinematic Shooter galary adventures really bore me. And one level in COD MW2(one towards end at presidents building) felt no more than Virtua cop 2 in core gameplay. Even UT99 is more 3D than that.:) Planescape Torment is like a reading experience(I am playing now), though a great one. The most reactive realtime interactive FPS games I have played are UT3 and Crysis first 3/4 korean part(ranking at top), in part due to very good AI also.
