I thought it would be a good idea to size up different companies and their support for the Switch so far. To see who is talking big and who is giving actual suppport.
This list is probably incomplete, so if I miss things or have them wrong, please mention it so I can add/correct things. Also mention if you want this updated or it is OK as a one-time thing.
As game isn't the same as another game, I mark some things with formatting. Here is what I use:
- million-seller on Switch
- Nintendo-exclusive
- no physical release (if only physical in some region aka Okami only in japan it is also italic)
- (limited release) (only cloud or japan-only)
I list already released games and announcements separately.
So, let's get to it.
EDIT: Formatting turned not out as I intended, so sorry for the mess.
