I spent my first $ on this game last week ($8 on the last day of RTTC to help buy GNs to get the last card). All in all, I'm not opposed to spending money but it would only be for situations like (GNs for RTTC or credits for HS for RC). I'm never going to spend $$ on packs because it just isn't worth it in my eyes. Besides all that, I actually like the grind and prefer to grind my way to good cards instead of just buying my way to them.
