So , youre basically saying youre tired of 98% of all eroges , including nukiges.
In any case , i think full blown dating sims are for you then. Though keep in mind that many of them also have a crapton of text to click. Try old stuff but good stuff , like True Love for example. I'd go on a stretch and say try Sengoku rance as well , but im not sure if its more than 1gb in size , probably is. That and it also has loads of text , but its more focused on comedy and the strategic/RPG side of it.
...or you can always go pro and get Rapelay.
