We never asked for it, but unfortunately, money speaks louder than sentiment when it comes to toy products, or in this case, the lack thereof. If toys aren't profitable for a toy company, then those toys get the axe. Simple as. Doesn't matter how much faith the people who actually did buy and enjoy them have.
LEGO should have never cancelled G1? Why? So that they could start bleeding money continually producing toys for a line that was losing ground after going for 10 years? That wouldn't have been a very smart business decision on their part.
And yes, G2 certainly could have had potential for much more, but only if the line had been more successful.
It's less that we're acting pessimistic and more that we understand that the conditions were not favourable for G1/G2/Constraction. G1 was on the decline and couldn't keep going forever, G2 could not live up to G1's legacy, and Constraction as a whole was suffering for it. You need to face that reality, too. The heyday of Bionicle and Constraction has long since gone. LEGO needs to focus on what is currently working for them, not trying to appeal to a minority who just want to relive their childhood.
