First, I LOVE your games - I have played 100's of hours of Eternum and I can't wait to play it all over again. Once in a Lifetime is so great - totally different so I won't waste your time (and everyone else's) by comparing them - you shouldn't. They are both amazing. Enough said.
There are a couple of things that I would like to see - sexually - that I haven't seen you do (or at least there's not enough in the games)
1. Anal - anal play, especially eating ass (some of the girls are so hot you'd have to...), and some good old anal sex (straight sex)
2. 3 somes - whether 2 guys and a girl or 2 girls and a guy (I think I only saw this once in Eternum)
3. Light bondage or a bit of spanking - not crazy about hurt or hardcore, but a little slap now and then never hurt anyone ;)
Last thing - most of your women have very large breasts - could you have a few that were like nice B's or even A cup size - it's just normal - and your Butts and thighs are very thick - I love model-type bodies (tall, slim, nice butts but smaller with smallish breasts)
Anyway, I am probably the anomaly in all of what I am saying, but I just had to throw it out there - even if you didn't add any of the above I will always play your games and will remain a TRUE FAN... your games are head and shoulders above most every game I have played. Thank you for continuing to make amazing stuff.
