That pretty much already happens. When you finish the game, you get the simple text ending and after that you get popups saying what things you unlocked.
As for the names, I will probably just show the "???" slot and after you scroll on it, a text with "End the game with 999 units of food" will show up. To keep things a little mysterious, even though most unlock conditions in the game right now make sence for the item you are unlocking.
The pub is actualy pretty realistic. It is empty most of the time, but on some days characters decide to hang out there. It is pretty much full once that happens.
And those two guys will have a purpose in the future. Mainly talking between them selves and you just listening to them. They will talk about things you did, things that happened and things that might happen. Kinda like newspapers.
