will there be more games on gog connect????

Hopefully. We've been given no indication so far of how frequently to expect them to happen, unfortunately. With luck they have another one lined up, waiting for the post-sale support rush to die down. But that's pure conjecture - nobody knows when the next one will happen.

It's a publisher thing. If some of the publishers decide to do some gog/steam connecting again then there will be more games to connect :D

when i did try too check i did not find any more only van helsing i did get
the other games i did have

There, but for the grace of GOG.
