Not sure if this is the correct place to post this, but I guess it fits in the Distribution category.
So, my question is - what hardware should I choose for a server that would host a game made in 3DGS. What I should focus on, which pieces are the most vital?
I know you need a description of the game.
It is an online game, much like an MMORPG (That word hurts your ears doesn't it?), but with a huge difference. The camera is static and it is played like a website-based online game. Which means, that the positions of all the clients are not updated, and that cuts down on packet sending a lot. So basically, the only updates sent are the player's inventory items and player's stats. The updates are not sent in a period of time, but as soon as something changes, to evenly distribute the load on the server. Also, all the vital computations (attacking, item usage etc.) are happening server-side (for security reasons) so that adds to the load a bit.
And the packets sent during the play consist only of pure variables and skills, no arrays, no strings. (I just thought it would be important for you to know).

That should be enough information. If you need to know more, just ask.
Oh, and could someone be so kind as to also tell me, how many times would the bandwidth usage increase if I were to add a moving camera and update the client positions? Just wondering...

Thank you.

EDIT: Just as I had posted, I forgot to add, that the server will be used to host my website too and also all the game files so people could download them (The game will be free). I guess that is a vital factor too.
