I'm a v8er and I enjoyed that time a lot.
It wasn't "better" though. It is just a rose tinted past for most people. It was nicer for some because it was a smaller community, there was a free market of mods (which was good and bad), and there was just less bullstuff.
People RP'd better. CityRPGs in v8 were basically just a city build and a cash mod which was tied together by the willing roleplay of the players. Where as now you get over produced mods and idiots who bounce around asking "how can i get moeny pls" and missing the whole point.
Blockland now is great because of events, the bug fixes and improvements, the better file download system when connecting to servers, punch packets and UPnP, and many other things.
I think v8 was just the best of Blockland before it took the next step in its evolution. In my mind v8 to v9 was about as big of a milestone as Vanilla to Retail. I believe v21 is going to be the equivalent of v9 for the generation of players now.
