I haven't played a 4e adventure and I haven't read the 4e books yet. I really appreciate your experiences and your opinions. I think I have got an idea of the characteristics of the new 4e system but I will read the books in time to understand it better.
Beyond the discussion if the 4e is a better or worse system than the 3.5e (for D&D type of worlds) I believe that you all agree with some facts:
1) 4e is incompatible with 3.5e;
2) 3.5e is a flexible system and it could be upgraded by fixing its weak topics;
3) 3.5e is an open system (due to OGL) while 4e is controlled by one company. 3.5e could be supported for ever by companies or creative people;
4) 3.5e is currently supported (Pathfinder RPG);
Concerning the (1): I enjoy reading my current library of worlds and adventures (written in 3.5e format). I don't care that much about the system. The system is just the tool for our game. It has to be appropriate to express the D&D type worlds and characters; it has to be of a certain quality to support an enjoyable session; it has to be flexible to let us adjust it to our ideas etc. The system (as a run-time system) is going together with a specific format. If you change the system, you change the format and you are making your library obsolete. I don't like it. I prefer to add new worlds and adventures, not replace my old ones with new versions.
Concerning the (2): Note as an example, that the 3.5e was flexible enough to be adjusted to express the OGL Conan RPG.
Concerning the (3): Now that I have experienced the open air of OGL, I really don't like to be depended on the interests of one company. Note that sites like the
www.d20srd.org, supplements like the Grim-n-Gritty, utility software like the HeroForge and hundreds of worlds, supplements and adventures wouldn't be there without the OGL. By the time that the owner of the 4e will decide to change it to 5e (and make your 4e books obsolete), the 3.5 could be there and fully supported (possible upgraded to incorporate new ideas and mechanics);
Concerning the (4): I think PAIZO Pathfinder RPG is a nice upgrade of the 3.5.
