Is it possible to make a Text Based game with only HTML and some PHP for chat?

I dunno any languages besides HTML. =.= yeah Im a newbie.

Well it depends on what you mean by text based game. If you mean some kind of adventure game where you are in a cetain location and you select an option for example:

you are in the castle and a dragon walks by:
a. follow the dragon into the dungeon
b. leave the castle into the wilderness
c. slay the dragon

Something like that could be done with a lot of html pages yes (kind of like the books that are like that). If you wanted a player base that you needed a login etc... you would need php.

Haha... reminds me of MUDs from back in the day...

Most time I've ever spent on a library computer terminal.

Well, what kind of game. Dungeon games like alex suggested can be done with a ton of HTML pages. But if you want a more functional game, you must use PHP and some form of database or flatfile. I would suggest waiting a while before making a game considering you only know HTML. For a good game, you need HTML, CSS, Javascript, and PHP, along with some SQL knowledge for your MySQL databases.
