If you aren't chasing time, it is definitely one of the best and affordable (esp if you are 25 or under) ways to see Europe! I personally love train travel Have you already checked out Eurail.com? You can check out the different passes to see what would be best for you. When I went I got the Selectpass (you choose 3-5 bordering countries and get a number of travel days) as I only traveled within Western Europe.
If you want to maximize your sightseeing in the cities, you can certainly go by plane. The thing with Ryanair and easyjet though, is that you have to keep checking everyday to get the best/cheapest price. Also, I heard that they are pretty strict with baggage.
In any case, have fun!!!! I really enjoyed Europe. I'm already planning a trip for DH and I even though it'll be at least a year before we can go! LOL!
