I have no knowledge of the original pre-retail Blockland, but even without it, I can tell something has changed.
Maybe it's just age. I started playing Blockland aged 13 or 14, and two years later perhaps I enjoy other things, an all too real tale for things I used to like that now either bore me or I can't find time for.
I remember first getting Blockland, happy to finally have my own key, and joining a community of under 7000, before events, physics and many of things a whole bunch of people including myself think nothing of at times. When I joined, if someone was annoying, it was a case of banning them for a while and solving things later, not resorting to drama flaming for several months until someone has the sense to end it.
If I could choose a time when Blockland was best it would be just after events came out in v8/9. Nearly everyone was nice, the new system combined with the ignorance of the users made everyone equal, just for a small period.
Some things have changed for the better, but the fact is that a couple of years ago I said I would play Blockland forever, a prospect which is to begin with flawed, although I planned to play for a long time. Now, in all honesty, I'm not so sure. Something's different that I just can't work out, somehow turning me away from the "good times" to other things.
Like I said before, if the whole inequality thing didn't happen, calling people noobs, banning them for no apparent reason etc., I'd enjoy the game more. I'm probably just jealous though, taking in the general ignorance of BL_IDs and reasoning thus:
"If he's ID 14k and I'm only 6k, then how come he is liked more, how come he can build better?"
Pitiful, "IDist", but true =(
