Off memory if you wanted a game like that, then php, html, csss, &#106avascript should be all you need to get a start, once you have it developed, if it does turn out popular, then you can loook at futher technology to enchance the gameplay/performance

Ive considered a web based project, but im no artist and i dont know any ^.^

yes that was my general plan if it gets popular but the whole point was the creation of the game in php,
if what i wanted couldnt be done in php then id changed what i wanted to do
