Nothing buggy at all.
I have absolutely no problem with someone who has put so much time and effort into their work making something from it.
I can't believe you didn't see it coming. Or had you not noticed that ISXEQ2 is a subscription service and has been for quite a while. He's even posted that at some point he may take it subscription.
However, it is your choice to complain. All you really need to do is learn how to code and reverse engineer the game, as Amadeus does, and you can create your own version is ISXVG. But, since you most likely lack the skill, well... too bad.
It bothers me when people are so willing to bitch about having to pay for something that helps them, that they cannot on their own create. I suppose you would gladly give away for free the work you do, right? That's what you're asking for when you complain about a measly $3.50/month. One fast food meal a month, or a couple of bottled waters or sodas/pops/cokes. If you cannot deal with that, then you shouldn't even be paying for the subscription to IS, or Vanguard. :evil:
