Paying for say an early access indie game that is still in it's dev cycle I am semi fine with, but a game that asks you to pay to GAIN early access to play said game that will also be F2P is a big no-no in my books.
Also I have noticed that some of those games that do go F2P offer "founders" editions where you pay a chunk of cash to gain absolutely everything, but then it turns out you din't get absolutely everything, is also another big no-no from me.
Step right up come on in, feel the buzz in your veins, I'm like an chemical electrical right into your brain and I'm the one who killed the Radio, soon you'll all see
So pay up motherfuckers you belong to "V"
