This may be the reason why you haven't seen very many FPSC games with a good storyline or any at all.
It can take years to make a top notch game...and that is for a company with who knows how many employees.So you can imagine how long or how difficult it will be for one person to do it by himself or herself.
On the other hand,Mr. Love,if you care to show us how it is done...
or rather,as the saying goes,put your money where your mouth is, and show us how it is done then that is fine with me.
Nothing personal.That's just an observation.You can either complain and accomplish nothing or you can do something about it.
On the other hand,there have been a few FPSC games/demos with a storyline.
Then again there are only so many types of stories one can come up with.
While a storyline would be nice there have been several great first person shooters with little to no storyline.
Obviously this is a matter of opinion and there are those that will disagree with me.
