Thesis statements and you

This has always been my biggest hurdle when writing a paper, getting the topic narrow and detailed enough. Once this is done I'm good to go, outline flows, paper pretty much writes itself (assuming I have the research I need) and I"m good to go, but this is like a mental block and I get nervous.

This paper has to have an interdisciplinary slant but still relate to my major. I worked in the video game industry for a few years and pretty much everyone I know in San Diego (that I didn't know before I moved down here) still does. Because of this I decided to write about the issue of buying and selling virtual items for non-virtual currency, being referred to in 'the industry' as RMT (Real Money Transactions). I am going to illustrate three different attitudes the companies can take and those effects on their games success and popularity, and then touch on the legal aspects. It's putting that into words I'm having trouble with.

A thesis can be a whole paragraph right, not just the sentence at the end of the first paragraph? Is it ok to say 'this researcher will be looking', is that pretentious? I know the first person isn't acceptable, I do remember that much from that English class 16 years ago (this is where I put in the omg I'm old speech. I'm too lazy to type it out again so just interject your own, it's more entertaining that way).

This is my goal today, to have this first paragraph(s) worked out so I have a direction. I'll post more when I have it done. I'm actually going down to the college library today to get some books, how quaint!
