Is the use of patent in the gaming industry reasonable

Recently some game studios have began applying patents on the mechanism used in their games.
This means other studios can’t make use of similar styles in their games.
Personally I think this is a problem because the way the game industry progresses is by making previous games better in new forms.

What do you think ?

I would say it depends on what property the studios are filing for patents. There are studios that wish to maintain a unique mechanism that they produced just for their video game. The same has started happening with VFX studios as well. However, I agree that this will be a problem when developers take advantage of this and start patenting the most basic mechanisms and locking them from access to others.
