About wild magic potentially not working.... The odds of a wild magic surge are crazy low. If you arent forcing a roll the odds of it showing up are a 1 on a D20 so 5%. And only lvl 1 and up spells count for that, so not for cantrips. I wouldnt be surpised if the number of lvl 1 spells cast in that demo were less then half a dozen. times 5% of it happening per cast and the fact that it dident happen yet isent really all that strange tbh...
If done properly, surges are not uncommon - the 'design' is that a player who wants to surge frequently should be utilising their tides of fate at every opportunity, and the DM should be reciprocating by calling a surge immediately when they cast a levelled spell after doing so, and recharging their tides in the process.
For a video game translation, I'd strongly recommend that that be automated - that using Tides simply causes your next levelled spell to surge and recharges tides, guaranteed and automatically.
