The way you say that implies that you need text even if you have an imagination. If you're imaginative enough, you wouldn't need the text. Or the images. Or the game. I will agree that a game shouldn't rely on it's players having an imagination. However, the game already stretches the limits of the RMXP engine. It seems greedy to ask for more.
Frankly, after playing it a bit more, I'm finding it hard to like Erotical Night because it loses the RPG elements in favor of the animation. The random encounters are fine the first time around, but then they just get tedious due to the main character never actually getting any stronger. All he does is find better/more items to equip or spam in battle. Besides, the further I get into it, the more goofy male undergarments I find, the less I care to look at the guy's ass. I'm a sellout for costume systems, but only when they're female costumes. The "I'll appeal to male players by putting them in control of a perpetually near-naked dude and give them lots of ways to keep him nearly naked" concept isn't working for me. At least the opening was funny. I chuckle whenever I think of the thrusting exercises.
I'll see about getting a thread on SQDT or SQT or whatever it was later today. Hopefully by then I'll remember the full title.
