Mr Flowerkohl,
Fair comment - though FPSC has not been designed from the bottom up to specifically meet the needs of those wishing to make unique games using all of their own content. Its not even - particularly designed to meet the needs of any kind of indie game developer of any stature. Thats a commercial decision on the part of FPSC. Its designed for click and play - aimed at a mass market and generally people who will buy it because they have a general interest in games and may like to have a go at doing so for the purpose of non professional and entertainment use - and they can now do so - that aim V1 will meet. TGC Objective achieved.
The rest of us have a bonus - we have a low cost engine we can use and with a lot of hard work (just like any other engine) maybe achieve what we could not with any other indie engine - make a game of something like a commercial title quality.
Thats the situation.
Now as to wishing to see FPSC become more - so that it meets with the needs of everyone including serious game makers and also accommodating the requests made for additional features and functions to satisfy all of those is a rather larger task.
You will have to have patience beyond V1 I'm afraid and make your requests following its release. There is no point in requests regarding features until then - V1 feature set is now fixed. Though debate and comment - well thats your right.
In fact I would agree that if possible it should be easier for more people to get their own content into FPSC including various types of Animated entities.
I myself like MD2 and many other formats - unfortuntely in the case of MD2 its not a format you are likely to see future professional game engines use a great deal. Its use is more likely to likely to diminish than not.
It certainly is possible now to : Make your own games with your own textures , models , entities , weapons , sounds and screens and decals and so on. True its extremely time consuming and sometimes difficult and you may need to have and master a lot of additional software as with any other indie engine.
Hopefully following V1, when by and large its product objectives will have been achieved - development can proceed that will provide perhaps more in the way of support for those wishing to take a more professional approach to unique game making by including easier implimentation of your own media in V2.
