I work for a company involved in the games industry. You'll probably find more money in the financial sector though

Almost what i expected. I got a 34k offer (same industry) with good benefits but am unsure if its worth the move. Main problem seems to be the rent which is ridiculous if you want to minimze commute time to the centre.

I think with most places in London you're looking at a 45min-1hour commute, unless you live REALLY close in zone 1 or something.

For me my commute is as follows: -

20 minute walk from house to tube station(could take a bus which would take 10 mins, but I prefer the exercise) 15 mins on the tube to Bond Street 10 minute walk from there to work

Financial sector in london typically goes from about 30k (entry level grad) upto about 100k. Or if you're contracting day rate is normally in the £500-£800/day range.
