I only came across the website Linux Game Publishing recently and being a relative newbie to the Linux scene I was very impressed that a company is trying to give the user the opportunity to get some professional games. Yes I know that some people frown on paying for software on Linux but I think it gives the user the choice.

Anyway my question is has anybody played any of these games, I was looking at X3: Reunion and Software Tycoon. I thought that X3 looked very like a modern version of Frontier Elite 2 (please correct me if I'm wrong) and that Software Tycoon also looked like a good game. I don't mind paying for games, however I'm not willing to pay for dross like Knights and Merchants which was dated ten years ago when it arrived on windoze (I seem to remember thinking poor man's settlers and that must have been released in about 92-93).

Or if you have not played them can you recommend a good website that reviews these games run on Linux.

I recommend that you try running the games through wine first, because LGP seems to like overpricing ancient games (ones I haven't even heard of). They want to sell them at the original price 10 years ago ... today you can find them in the discount bin for $1, maybe $2. Try them through wine first.

The games are the same on Window$ as they are on Linux, they are either run through wine or are ported, like what LGP does. There is no difference between the game played on Linux or Window$, except for maybe a few wine bugs here and there. So any review of the game will work. I usually look up games on ign, and read the reviews themselves not the score. Look for bad reviews and see what they complain about, verify the claims, if true, can you deal with it, if not, don't buy the game (that's my strategy).

Check out http://www.phoronix.com/. Phoronix is a great hardware review site for linux. They have frequent articles about linux gaming also.
Click on the "articles and reviews" at the top of the Phoronix home page:

and scroll down to "Linux Gaming" to see lots of articles and reviews of linux games, including games from LGP.

I purchased the "Cold War" game from one of LGP's retailers. LGP continues to support the game. It runs very well in Slackware 12.2. I agree with H_TexMex_H that their prices are a bit high. They have a much smaller market than Windows game developers though. So I guess they have to charge a higher per unit price to recover their costs and make a profit.
