Did you ever have to play a game without being able to read it? How has it affected the experience or how do you think it would affect it? How "accesible" do you think games should strive to be regardless of the language they are set.
While the most important thing is arguably the gameplay, it just so happens that part of the Rare experience are the puns and dialogue, that some times may be important in order to know what to do.
Games like the first DKC and Battletoads are very intuitive and playable anywhere, but I wonder if it's even possible to beat Banjo-Kazooie without reading the dialogue unless you are willing to endure A LOT of trial and error.
