The games market is quite a good one in my opinion, it's one that I am in myself. That being said, I doubt very much that it would be a viable drop shipping business model, as to get any sort of decent margin you need to be investing in large loads.
Take a look around your local area, you may well even find a Video Games retailer that you can pitch the idea of drop shipping to. You don't have to tell them where you are selling, you just have to ask would they be happy for you to b an agent and supply them some sales. Of course part of that whole agent thing is getting the games at a reduced price.
You would be stunned at the amount of business opportunities that you can dig up if you actively seek them out. I've had my nose in plenty of doors myself lol, and while sometimes it was a waste of time getting out of bed, other occasions putting my nose in that door has taken me down some extremely exciting avenues.
Cables, another strong market, but again, I think big wholesalers buying direct from China would be extremely hard to go up against with a drop shipping model.
I have a business partner that buys by the container load form China, and he has his margins cut to the bone to compete in the UK market. Very strong turn over figures, but he needs those strong sales to get any sort of half decent profit for the effort.
Brand name clothing is an interesting one. If you had some capital to work with I would be suggesting that the surplus market is where you should be looking. Lots of things you need to be watching out for when buying liquidated products, but that is a great market to pick up branded clothing.
Anyway, we have a starting point now so that's good. One of the support team will most likely reply to this post with some supply leads for the avenues you have indicated, if they exist of course, but you can contact firstname.lastname@example.org with your product preferences to be absolutely sure someone is digging for you.
Once we find you some suppliers for what you want to sell, then we can walk you through the research stage ; )
