I put you in situation (Try to put yourself in my perspective): Imagine for a moment that you want to create a full conversion of doom aimed to cooperative online style with emphasis on teamwork and new game mechanics (you know how to do it and you got a team willing to do it). You and your team are going to do all the new code, maps, new mosters sprite by sprite, new sound effects and a complete new soundtrack made by yourself. BUT! here it comes your big dilemma:

Is worth investing a year making a new cooperative mod megawad? What about the player audience? Doom online seems to have stalled in the same 4 game modes, more curious is to see how megagame has even more audience after all. It is worth spend a long year of work, graphic design, musical composition, mapping more than 30 maps, coding hundreds of lines if not thousands and testing again and again in a debug loop, bug fixing, updates and the never ending list "of over here" and "of over there"? All of this work... How many people would play it? 10 players? Perhaps I am very optimistic that of those 10 players, 5 of them do not invest more than 20 minutes playing your mod, the work of three people during a year of dedication (In fact, there are also personal tastes here indeed).
Zandronum has incredible potential as an online gaming platform for mods. But where are the players?
The big question we have is: Should we work on a doom megamod cooperative online aimed for play it with Zandronum? Or maybe we should design a new game from scratch: a flash game or HTML5, easily shareable, easily embeded in every website (that assures thousands of audience, followers, supporters, even an economic remuneration) Or maybe we should desing a multiplatform game for Win/Mac/Linux? thats the big dilemma here.
What do you think honestly? and by your own experience the effort is worth?
