I found NOVA to be completely useless, and you are good with games so I think you will be of the same opinion. The best prep for RC is the LSAT SuperPrep. There is a lot of really good information there, I highly recommend reading it multiple times. One suggestion for when you read it: within the text they refer to actual passages from past LSAT's and provide the test number (but not the full passage). I think it's useful to refer to that particular preptest, read the passage and try to answer the question before looking at the explanation provided in the SuperPrep. Examine your logic/thinking and compare to what they think your logic should be. Their LR section is also pretty good and in no way contradicts the LRB.
