Well, I must say, I´m getting a bit confused now, because everybody is talking about the "new 3D engine" and I get the impression that people are getting mixed up with realtime 3D à la Farcry and modified 2.5D engine à la "Geheimakte 2".
A Vampyr Story, for example, is a 2.5D (prerendered backgrounds & 3D characters) adventure which was developed using a 3D engine.
So, to clear this point, is "WME 2" going to be a real time 3D engine, like say "Memento mori" uses or will it still use the 2.5D technique, but based on a 3D engine for better lighting effects, shaders, shadows, character animation, wide screen support, dynamic lights & camera and such things?
I personally really hope that WME 2 will stay 2.5D, because if you want to create a realtime 3D adventure, there are other tools on the market which are afordable. Sure, they won´t be so nice and simple as an engine that was specially developped for adventures, but it can be done, without too much trouble.
But there is nothing on the market to develop a modern 2.5D adventure (sure if you want to pay 20.000 €, then try ADGS4 ;-)) ).
