There are currently 600 alias types (e.g. Alternative spelling or French title). However, only 20 is offered for selection in the edit form. Please add more. I mainly need Czech title but I think that all the languages should be in this list. This is the list of alias types with >=10 games and the number of games using them. Only those marked with * have their option in the edit form:

On my website, I display only aliases in languages the user speaks. Having all the translated titles as Alternative title hinders this.
