Pizza UBs better than current burial tomb? Are we even playing the same game? -15% gold cost +3Gold per TR better than +7C +5S +2T per city that comes much earlier? How? Especially considering by this point in the game Venice shouldn't have money problems period, how is that measly amount going to make a change? I never take that one.
The +2F+2T per improvement one is actually good... Except Burial Tomb means you only need as many cities as Enrico has great improvements to get equal tourism - except you get it earlier and can easily make art combination to get more. You will get less Food, yes, but in no way is 2 Food better than 7Culture and 5 Science. No matter how you play, you can't say it's otherwise. The Arsenale is cool, but not "Get as much Science as all the Scientific buildings of Ancient+Classical era combined, while getting way more Culture than all Ancient+Classical era buildings give" cool
-10% investment cost, +3 gold per TR, +4+ WC votes, merchant specialist
or
+15% production +6 defense +unique promotion for all ships
or
+2Food/tourism for all GPtiles/villages, free museum(slotwise), artist specialist
Along with the bonuses already from Piazza, yeah they are far superior to the Burial tomb, and far more interesting.
Jellingstone being allowed to be built in other locations hardly matters because it won't give your landlocked cities any palpable benefit anyway. It gets +2 base C, which Tomb also gets. The +5P+5C part requires actual effort, will not happen every turn, but then I admit it is more interesting than the Tomb.
You've never placed an inland city with a few coast-tiles in the third circle or even a fish or two? Happens quite a lot for me anyways.
The reason why the production and culture from kills feels more interesting is both because they scale with era and because both the yields feel like something of substance, you're going to expand your borders faster and you're going to build units/buildings faster if you kill units, that's interesting. I'll admit that as a bonus it isn't exactly fantastic, both those yields drop in value a lot faster than they scale with era, but they remain interesting. And the +15% GPP part is solid.
I still don't understand how the proposed tomb is bad. Holds its own in its era, gets Tourism which IIRC no unique building of that time gets as well as combos, and Faith.
It definitely wouldn't be the worst UB anyway, considering it gets decent yields of its own time and would get Skola-tier yields once Archaeology is researched.
Because even with the current yields on it, the Burial tomb is about as interesting as a bag of rocks. Without the Burial tomb, their current UA would be the worst one in the game, a 20% bonus while building wonders? That's like 1/20th of the time, meaning on average you're receiving an extra +1% production from it. Synergy with GA that doubles the effect? Without any GA-triggers in the kit that's also completely meh.
It's not as if you can control when you build wonders anyways, they are available at a specific moment and at that moment you either decide to build it or decide not to, you can't wait for a GA to trigger and you can't exactly trigger a GA yourself (unless you use an artist).
Don't get me wrong here, I absolutely despise the current Burial tomb, it is absolutely not interesting in any way, shape or form, it also got reverse synergy with the rest of the theme, you generally want to go for tradition/aesthetics to get the most out of the wonder and GA bonuses, while you clearly want to spam as many burial-tombs as possible all over the place. Optimal strategy here would be something like capturing cities, annexing them, building burial tombs and then razing the cities to get city-count down.
To me the Egyptian unique building is not interesting, the Egyptian unique ability is not interesting and the Egyptian unique unit is not interesting. Nerfing any part of the civ right now would move Egypt from "not interesting" to "I have to mod this civ out of the game so the AI doesn't get stuck with it by mistake".
Also, please stop comparing it to the Skola, the Skola is garbage.
