To allow express to handle form data nicely you need to ensure you have bodyParser included like so:

var express = require('express'),
    app = express.createServer();

app.use(express.bodyParser());
//the rest of your configuration

Then in your POST handler you can access the form body through the Request.body property like so:

app.post('/game', function (req, res) {
    res.render('some-file', { name: req.body.name });
});

Also you'll need to use a templating engine (such as Jade) if you're intending to output the form data in the response.
