Strictly speaking you should have registered within 3 months of starting trading. (Not sure how long you have been trading for).
First thing is first. Head over to this page:
http://www.hmrc.gov.uk/forms/cwf1.pd...asselfemployed
Fill that form out and send it back to HMRC. That will then mean you are registered as self employed with HMRC and they have you on their records, "officially". The next thing to do is to look into National Insurance contributions. As you have a full time job now I presume you already pay these with your current employer. You will need to do some research on this and see what the implications are.
VAT registration isn't required until your turnover exceeds whatever the given figure is for that year (£61k or whatever it currently is). It isn't necessary to register for VAT until you reach that figure, in my experience very few register until they hit the time they legally have to. Registering PT Games can be done but you can quite easily state you are "trading as PT Games" until you formalize an entity later in your business. The other alternative would be to go to a Limited Company but much like VAT I wouldn't advise doing this until you have out grown the "sole trader" or basic capacity of a start up.
Registering a business is actually very simple. It only really gets complicated when you register limited companies and start dealing with VAT. Don't forget that as soon as you register as a business you will be required to fill out a tax return each year - although this may seem standard, don't forget to do your accounts properly and ensure that your books are up together in case they ask for them after you submit your return.
