My boyfriend behaves strangely in comparison with his exes?

When I first started dating my boyfriend, everything was going incredibly fine. We have a long distance relationship and often love to chat everyday. However, the one thing he absolutely forbids to do is play any sort of games with me.
This wouldn’t bother me if for the fact that he also loved playing games and talking on voice with his ex-girlfriend. They used to talk on call every other day, play games often, and video chat.
We haven’t done much.
He also gave her a lot of thoughtful and beautiful gifts he planned to give her. This wouldn’t be the case with me.
Any advice?
