Honestly, I've not played a single F2P game that 'required' any purchase just to make normal progression. Sure, most F2P have a cash store for extras and the like, some to the point of being Pay2Win, but 'most' are reasonable. I'd love for them to cite specific sources, and then when faced with actual spending reports and the like, decide to continue to butt the hell out and let the free market manage itself.
If moron A playing F2P game 1 spends $100/month on various extras and cosmetic items, should the government regulate that?
If moron B playing F2P game 2 spends $100/month for progression in said game, but is too stupid to use Google and find 1 of 1,000 other similar free games that DON'T require $ to progress, then is it necessary for the Gov't to regulate? You're still playing the game for free. It may not be fun and you may not be able to do much... isn't that how a demo used to be? False advertising? No. Will the game last, probably not, without a progression system overhaul.
Remember the demo disks in the back of the PCGamer magazines? Those free game portions to get you enticed, but alas! You have to PAY to progress the rest of the game. Paying $40-60 for full access at once, or 20 micro-transactions of $1-3 to get the same progression..
Again, the government should regulate this why? And I mean ANY gov't, not just US or EU. Sounds like an excuse for the ruling parties to sit around a 'investigate' these F2P games on the tax payers dollars for a year or two just to make sure there is no funny business going on.
