My story:
I was 33 when I signed up for T2G. I was renting a flat at the time and stuck in a dead-end job. I had set my goal on a career change and I chose the games industry as my attempt to get my arse shifted into something more enjoyable and something I could take pride in. I did a fair amount of research and T2G was near the top of my list already as my younger brother was already signed up with them and in the early stages of his personal (and fulfilling) journey with T2G. At the time he recommended them to me.
I researched the hell out of the games industry and decided I wanted to be a level designer, I registered my interest with T2G and they eventually, some weeks later, got around to sending someone out to me.
By this time I was already mentally committed. I was preparing to move out of my flat into somewhere smaller to help me afford the cost of the course. I had been learning UDK and the whole sales patter that took place was largely unnecessary. What I did object to though was even that given my situation of moving house, the salesman still tried to insist that I sign up there and then. I lost count of the amount of times I told him that I simply could not afford the £100 enrollment fee. He even suggested I borrow the money from a family member!
In the end, he left without his money and I was pretty angry. I wrote to one of the old DR staff that used the T2G forum a lot at the time to complain about this and he promised to forward this on.
I guess he did - I got a call from the area manager the following day. After some negotiation which mainly involved me telling him, no - I did not want to sign up while I was moving house we did eventually agree that if I paid an enrollment fee then my actual course payments would be deferred for 3 months. I naively agreed to this and, of course thereby threw away my "cooling off" period, as I was far too busy moving house to worry about the course at the time.
So.. I was now on the Game Designer course. A course that I was promised would teach me all I needed to know about getting a job as a level designer. Well that was a load of bull. Level design, I later found out was not covered until section 2 of the course and consisted of - I believe, an entire chapter. Consider that a chapter in the world of T2G is roughly 3 pages and you get the idea.
I didn't like the game designer course 1 bit. It was a book that taught you how to admin. Not what I wanted to do. So I contacted T2G and made a request to change course. I was determined to learn something! I changed to the art and animation course because that was the course my brother had been doing when he recommended T2G to me.
I got most of the way through section 1 before it struck me... Why was I changing my goal to fit in with T2G's failings? I didn't want to be an artist, modeler or animator. In fact, I was completely crap at it. And so, about 14 months ago I dropped everything to do with T2G and did what I wanted to do in the 1st place.
I had essentially written off the £5k as a loss and not thought much about it - the mood on the T2G forum at the time I left was quite upbeat and the community was happy to defend T2G when it was called into question. It wasn't until I visited the forum again recently that I saw what was happening and that the mood had taken a turn.
TL/DR Avoid T2G. There are better/cheaper alternatives.
