My biggest wish for CoC2 is a way to track pregnancies, both for the PC and NPCs, much like in TiTS. And by that I mean being able to know when and who. While I seem to always go with the Breeder perk, to make the PC's pregnancies go faster, I'd like to be able to know right away when it happens. The CODEX in TiTS will give you the number of babies/eggs the PC is carrying and how long the pregnancy will last. I realise that we can't have a StarTrek tricorder-like CODEX in this game, but a magic one is doable. Make it a grimoire. One game I'm running now, the Champion has impregnated Gwyn, Lady Evergreen, and I think the Wyvern Girl. The last I really want to know if I've impregnated her or not. The PC has sexed her up at least ten times in the span of a couple of days, and I have no idea if she's carrying an egg.
I'd also like to know the number of offspring the PC has that aren't in the Nursery. I'm pretty sure there are 16-18 Hornets, 3 Alarune, 3 Harpies, 2 Tanukis, and maybe a Wyvern running around that 'I' don't see. I also think there are 10 kitsune my PC has had with Kiyoko, including Kinu, but I'm not sure.
Third wish is a way to 'fast forward' time, like the 88MPH cheat in TiTS. The 5 hour wait is okay, but what if I want to jump ahead 36 hours? Or 5 days? Or a fortnight (2 weeks)? That's an awful lot of times I'd need to hit the 5 hours button.
I have a couple more wishes, but I'll stop here, and I'll stop comparing CoC2 with that other game I've already mentioned 3 times.
