So i recently became interested in making my own multiplayer browser game with php and i was wondering if i needed money for buying things or could i just make a website on one of those make a free website sites. thanks
SWC runs a dedicated server, maybe two (one for the dev server), so that obviously costs money. Depending on your playerbase that may not be necessary, but to use PHP and mySQL databases you're going to have to pay for some type of hosting.
Not to mention the time it takes to code, create images, web design, etc, which can't necessarily be measured dollar-for-dollar but certainly has a cost of its own.
It's perfectly easy to run a small game or whatever off of a shared hosting account. I pay about $4 a month and have unlimited databases, subdomains, email accounts, and a very large bandwidth and storage cap (then again I've been a loyal customer for quite a while and some of that is legacy).
I think the biggest issue is ability. If you have the ability in PHP, MySQL and whatnot, the starting server costs shouldn't be much more than the price of a McDonald's value meal.
Pitch your ideas to the SWC devs. Maybe they could code an "In-flight Entertainment" button on the Ship Controls page, allowing long-haul pilots a distraction from those interminable Cap. Ship flights.
