Back to freedom while great, has a paywall before cheats and walkthrough. Community Service is sadly dead
Unfortunate that the walkthrough is paywalled, but genuinely I think it's one of the top HTML games around. Cheat in money using SavedItOnline once and you're set, and you can intuit
most scene unlocks save for some which the creator seems pretty fine with explaining in the thread anyways.
Last I heard of Community Service was that it is on a hiatus and not abadoned but I haven't looked at it in a long time so I could be wrong.
I believe it's on Hiatus still, which is a shame because it really had some great promise and potential.
In regards to games like College Daze I have found that
A Spell for All is similar and quite in depth / with a lot of content, and with a similar premise (kinda.) My only distaste for A Spell for All comes from the fact that I've been unable to finish my game both times and there's bugs / unclear paths oftentimes.
Patriarch is a good game for HTML as well, though could use some polishing - the dev has learned a lot and has disappeared a couple times but seems like it's his passion project so he'll always return eventually. Lastly we have
Become Someone, that's quite broad and expansive but can definitely be grindy if you're starting from the very beginning.
Editing: to come back, I'd also recommend
Incubus City as it's pretty great and complete - it may be repetitive, but once you really get into it there's a large amount of differences in scenes depending on background and thereby there's many endings as well.
