I see a small difference between I am fine with it and it is fine for me, which is the same difference between I am unclear (used to express doubt or confusion) and it is unclear to me: in one phrase the grammar subject is I, in the other is it.
For example, the focus could be placed on I to mean it is unclear to me, but it can be clear to others, or it is fine with me, and it will be fine with the others too; vice versa, the focus could be put on it to mean it is fine with me, but I don't know what others would think.
Most probably, both the sentences (the one starting with I, and the one starting with it) are understood to mean the same thing from most the people.

Finally, the word touch can convey an emotional, rather than physical contact (transitive verb, meaning 10).
To affect the emotions of; move to tender response: an appeal that touched us deeply.

Lose touch with reality implies you were once in touch with reality.
Out of touch with reality is silent on whether or not you were ever in touch with reality.
Probably not.
Just because someone feels an overwhelming need to play computer games doesn’t mean they’ve lost touch with reality.
Also, addict is often used in a non-medical way (especially with respect to pop culture), so a video-game addict might just be someone who enjoys playing video games a lot, but doesn't meet the clinical definition of addiction.
However, if your assertion is that in some cases someone is so obsessed with computer games that they simply no longer have any regard for the real world, then you could probably use it. But that would be an extreme case.
