Tits or Lilith's throne? Which is the better game?
TITS:
Content in TITS is curated and focuses primarily on hyper proportions and futa-women, especially if you decide to play with art on. There are other types of scenes and fetishes in the mix as well, just not as common. I find sex scenes to be of higher quality just because they are actually thought out and written by a person rather than added by code based on whatever body parts you have, though your mileage may vary.
Progress in TITS is steady and stable. It has been in development for a longer period of time and Fenoxo has an entire team backing him up. Alas, the old engine they were using (Flash) was officially deprecated due to it's age and security concerns and this forced Fenoxo to port everything to a newer one, something they are still in middle of (the newer version is still incomplete). The community has its share of writers as well, and Fenoxo sometimes adds their work to the game (with their permission).
Some years back Patreon decided to tighten the rules around what content was allowed on their platform and the lead developer caved in to their demands. Incest was removed and newer content comes with certain limitations in mind.
LT:
Lilith's Throne is a newer game being worked on by a single developer, Innoxia (though lately modders have been a big help too, some may even argue they do more than the developer herself does, and aren't even being paid for it...).
Its bread and butter lies in its customization, both in terms of character appearance as well as content toggles and tweaks. Sex scenes are modular and generate based on the body parts and fetishes of the participants. In terms of sex, TITS and LT are in the opposite ends of the spectrum. In TITS sex scenes are hand-written but offer no variability, LT has variability but lacks flair, meaning you're forced to rely on your imagination more often to carry it through.
LT's development is a bit of a joke (or sore spot) among the community. Innoxia is known for her inability to keep up with her own deadlines and getting side-tracked quite often. This results in promised content getting delayed for weeks or months in favor of her "spontaneous ideas". Progress has slowed down over the years and there are questions regarding how feasible this all is in long-term (i.e, whether it will survive or not). So far, all feedback regarding the game's pitfalls and suggestions have fallen on deaf ears, and half the community is liable to jump at you if you so much as voice your criticism... (though less so on this website).
The game is as wide as an ocean but deep as a puddle, and suffers from feature creep. There are a lot of fetishes and customizations options but they are mostly inconsequential as the game doesn't recognize or even acknowledge even half of those things in any meaningful manner. Most people who praise the game are newcomers who haven't become disillusioned with it yet... we've all been there. Lilith's Throne is one of those titles whose enjoyment comes with an expiration date.
Once the novelty feeling fades, you really only need to check this thread once a year to see if there has been any progress.
Both games have their pros and cons and several hours worth of fun, it all depends on what you prefer.
