Ah it is indeed yet another gog-games domain.. Not to confuse with gog-games.org.
Also while searching for the .to website I just saw a report of a user suspecting a malware infection after downloading a game there.
Honestly, seeing how many websites share similar domains I would be very cautious browsing them...
But the banner is indeed real.
Edit : For more transparency, Here is the reddit post being suspicious about this site :

But there is also reports that says its safe for the games but to be careful with the ads on the site that might lead to dangerous stuff. Probably a good idea to browse with a decent adblocker at least.
