well technically tomodachi collection ISNT tomodachi life, so i consider it as tomodachi life 2

Tomodachi Collection is still the first in the series (and it's on Nintendo Music, so it's been acknowledged at a worldwide scale), it's Tomodachi Collection 3

2 in my opinion

4, Actually. Because... 1 - Tomodachi Life DS 2 - Tomodachi Life 3 - Miitomo (Technically Tomodachi Life Mobile Port) 4 - Tomodachi Life: Living The Dream

i, who played the translated version of tomodachi collection, will consider it a tl 3

I believe it's 3 because of tomodachi collection if i remember well ^^
