even they (fanatical) have better deal, about 30 games with much lesser cost

Same here, I have a smattering of the games so would really like more bundles with individual keys.

And we know the answer, why?

Contact fanatical, they got nice support.

Bummer. :(
If you really want those games and Fanatical refuses to refund your purchase, you could activate the key via VPN.
Would be nice if you keep us updated about their response.

I thought about it again and it is an important heads up, the key doesn't seem to activate in Germany, as one of the included 56 games is very likely banned due to censorship reasons.
Even Fanatical is still clueless, because the bundle is continued to be sold in Germany.

There will always be a better deal as time goes by. It feels a bit too expensive to me, and I would wait for a better bargain maybe with separate keys for each game, but that's only my opinion. In the end it's up to you to decide. ;)
