Why is it that the title of this thread is the most consistent thing that comes through on game design. What is it about MMO's that enables people to overlook the multiple people needed to build, enormous sums of money to pay for it in the first place and still say with a straight face:
I have an idea for an MMO.
It isnt just this, Facebook / Twitter has created a storm of "I have an idea of a social network / website", fortunately they all drown in PHP sites, same goes for Flash with all those awful web games.
I do think the word hard / easy should be taboo when dealing with projects, completing any project can be time consuming careless of whether its a game or a website and think when people say something is hard what they are really trying to say is "its time consuming".
I believe that anyone can strategically achieve anything alone, whether a MMO or world domination (ok that was a stretch), theres been far too many cases in the world where a single person has achieved so much alone or at least in a much smaller team but sadly these "I want to make the next best thing" people usually have money on the mind, no real goal except to 'finish the game' and their project / plan is little more than a post it saying "Make WoW clone before birthday!" and typically their learning material is a "Making an MMO for dummies" book.
Saying that making an MMO imo is probably one of the best projects a person can do, it covers massive areas of programming and learning in general, its a fun effort filled project and even if you fail you will have obtained enormous amounts of knowledge just trying to make one, the engine / framework you will likely create will be reusable for smaller projects anyway so you could quite possibly fall back to a standard game too. However if you dont like reading, dont enjoy researching and dont have patience or time this is likely a bad idea from the start, making a game (MMO or not) covers a lot of fun areas of programming and maths, the learning experience alone makes it an excellent goal, sadly most people focus on all the $$/fame they will obtain and not the knowledge they will acquire.
