Who has thoughts on these oddball older games?

Lately I've picked up a handful of secondhand games that were five bucks or less each. I figured that for that price, I could take a chance, and if nothing else, I'd enjoy sitting down with a cup of coffee to set up the game and read the rules.

A lot of these are older games, and discussion online is pretty sparse, so I thought I'd ask here for thoughts from people who have played them.

Tower of Babel. Sounded like an interesting Knizia game. I played this once and really enjoyed it. Every turn, you have to help each other player in some way. So you try to find moves that help the other players the least. It's a negotiation game, but you can't talk too much, because if the other players know what you're up to, they can really extort a lot from you. Looking forward to playing this more.

In the Shadow of the Emperor. Played half a game with a friend just to get a sense of it. Seems pretty fascinating. Might be great? Also seems like a hard sell. I don't know what to tell people their goal is in this game, except "score more points". Definitely need to try it with a full 4 player table, hopefully I can make that happen someday soon. It's also the most aggressively yellow game I've ever seen.

Warhamster Rally. The theme seems funny. Maybe it will be a good light game for non-gamers?

Tempus. Got it solely because it's a Martin Wallace game (and $5). Most of the reviews online are about how the game was hyped a decade ago, and how it's not what they were expecting. I don't know anything about its hype, though, so this doesn't help me. Looks interesting, how is it?

Industria. Michael Schacht game, very cheap, why not? Looks like the rules are in english but the map and tiles are in german.

Genji. Funny theme, nice art, very cheap, why not?

Summit. Love the graphic design on this game. It's from the 1960s. Saw a couple comments online saying it plays like a precursor to modern euros, but not much elaboration. Don't know when I'd find a group to play it, but maybe someday.
