Word of warning the European Championship on in Poland/Ukraine next summer so prices will go up in that part of Europe plus hostels,trains etc will be busy and probably more expensive than normal unless you are going when it's over
Going on a 3 week European tour myself next year. I recommend going to Albania for shopping. Everythings cheap as chips as there's no tax
I went a couple summers ago - was awesome. Started in Amsterdam then went to Germany, Czech Rep, Poland, Hungary, Croatia, Slovenia, France. Think I'm forgetting somewhere, can't think off the top of my head.
Budapest is class, as is Poland. It's a bit morbid but going to Krakow and Auschwitz is definitely worth a visit. Croatia is decent - quite up and coming like, especially in summer. There's a place called Bled in slovenia which is pretty nice too. Best staying in Eastern Europe to save your pennies, but all in all was a class fair few weeks. Def worth it! You'll have fun whatever you do.

Mate, dont plan anythingTake it by chance. Its the best way!

As has been commented... Shopping in paris to start? Big mistake (unless the idea is to say to the girls you can't shop as you will have to carry it!)
Plan a rough route, with the odd fixed stopover ( every week or so) but don't be so rigid in your planning, you won't know what you like until you get there
Yeah but like we need to know where we go roughly.. some people want to go to Turkey, some to Latvia and some to Portugal
Ohh, you said a few pages back you had some info on places in Germany that you could PM? If you could that would be great, thanks!
