I wanted to create a text based browser game, so how should I go about? I can do programming in asp or jsp or php that is not a barrier, but I am unaware of what steps that one needs to follow while attempting to make such games. So please guide me.
please also recommend me a programming language for making the same.
One of the simplest browser games is just a series of static pages with links on each page leading to other pages. Often there will be some "story" on the page followed by a few choices you can make. Different choices lead to different pages.
The next step up is to use dynamic pages instead. When loading a new page, the browser can send some variables to the server and the server can generate a page on the fly. This saves you the effort of creating lots of similar pages by hand, and also allows you to do things like random outcomes.
However, if you want to keep a lot of user state (such as inventory, skills, or whatever), it becomes cumbersome (and insecure) to continually pass this from server to browser to server. This is what session handling is for: it remembers a user for a while, and lets you remember some variables at the server side.
If you want a more interactive game, you would need to look into Javascript and perhaps AJAX, which allow things to change in the browser without needing to load a new page.
In terms of language, I would suggest Python CGI, 'cause I like Python. Start with something simple so you can get a better idea of what you're working with, before you design something large.
Have fun!
