LOL, sorry.. I got the μ's first version 2nd single 9 years ago at japan(it worth about $300-400) and 1st single 5 years ago(it worth about $500-700), not a only 'trash otaku gamer'. also played llsif for about 4 years.
The problem is klab and bushimo still dont study any 'good part' from cygames and bandai, the model still suck like 5 year ago(just a little better than arcade version), and gameplay is really funny: you dont do any in-game purchase, you cant play any "hard-mode", it's a pay2win game, it's suck!
