Well friend, you can't do this only using HTML, and to think that it will be so easy is just stupid. First of all when you start making the game, you think about registering people, and then you think, how the hell can I handle form data, and be able to save it some where and be able to access it later. You look around the net to get to know how to handle form data in HTML, and obviously you find nothing because you can't.
So then my friend, I'll explain how you do that, you would know that all the websites are on a server, and when you type the name of the website, you are actually referring to a computer or network on the internet. Don't forget that the network of networks is internet. Now you know that you tell that computer to give you a specific web page on the website and it does, but the software that accepts your request and gives you the web page is called a web server.
When you give it some form data, it gets it, but unless it knows what to do with it, it discards it. Now here is where you can accept the form data, and not only that but create a game such as Poke Crater, because all the intelligence of the computer can be applied here.
You don't need to understand everything I just said, but you should know that the thing I was referring to needs some specific software. Your best option would be to go for PHP, but you could choose ASP, JSP, CGI (Perl) etc.
And another thing if yo get serious about it, don't try to set up a webserver at home, use some online host to do it.
So my suggestion was to learn PHP, it is very easy, and I learned it on my own from a book.
PHP:

Just in case you want to install PHP at home go to

Not to be rude or anything jonsploder, you are seriously not helping much, because if you say:
OK, your screwed. LOL! Do you know any code? like HTML, C++? GAMEMAKER? GML?
Cause otherwise you have no hope, sorry. At the moment I am making one, its online, got character select, stats, accounts, multiple accounts on only one - INGENIUS INVENTION! (If I do say so myself)
Umm, you better stick yourself with someone man, otherwise you dont have a hope, sorry.
then you are just discouraging a person. If he can learn some coding like PHP, like I did at the age of 11, it won't take him time to be able to make one. PHP didn't take me a long time anyway. I have attempted to create a game that he describes, and I had most of my work done in a week, i had to stop because I started to prefer making an MMORPG in C++. HTML doesn't matter much, though it will be important in the game, but he doesn't need to know all of it, and he does say he knows it. C++ is used in rare CGI program these days, I won't like that. And GameMaker and GML for website MMORPG proves that you know far less than improfane.
And your ways of not being rude seem more arrogent to me. For what you say makes me feel that you are just trying to prove what he said about you not helping much false, which is false. Saying that it is ingenious to make a game that you describe is totally false, at least if it is a web based game like he wants it. You, i suppose are making PT, atleast it says that in your sig, which is not a web based game but a GM game. Web based games are way simpler, it is only the movement part and the battle part which should take that much time, and even that is not too much. And in one post by improfane, I can say that he knows PHP and I suppose he will know a tonne more than you.
