I would suggest getting both versions , and then using T12 to import whatever you like about TR10 . Both versions are cool and have their own 'highlights'.Which version will or can you get first you will have to decide when you evaluate these answers and pick the one/s which suit your fancy. If you get one of them you probably will always be wondering about the one you did not get anyway. For me it is fun to play in TS2006, TR10 and TR12 when I want to. Now and then I grab an asset from one and stick it into the other and sit with the errors and broken and missing stuff that has to be fixed, ( my own fault mostly ) and that can also be fun if you can keep al your piggies in a row.I would have liked to merge the two versions and get what I like best of both for me, but if you read all the relevant threads you will see that there is a zillion things to learn to do to get that stuff right. If you are a computer boffin allready you are well on your way.
