Its not necessary to have in every game, however it can add a lot of nice flavor. I for one LOVED the "sex scene" with Tali in ME2. The build up to it was hilarious, with focus on the Quarian physique and how sick she would get, and Mordins doctorial advices. The scene itself was also very satisfying to me. To see normally shy Tali jump on top of me in excitement ^^. The aftermath was just as awesome, with Tali snotting all over the place and being sick like hell, but still pleased with the result. Absolutely awesome in every way.Dr.Awkward said:I'm going to be honest - Is something like this really necessary in the first place? Is such a thing something you want to define your series and must be in every game? If your PC and another NPC/PC fall in love with each other, then sometimes it's just better to let the player make assumptions on things such as sex. If these two people go somewhere alone where the camera can't see them, and the screen fades to black with a bit of an "audio cue", it's pretty obvious at what's going to happen, and at that point it's better to let the player imagine what happened; no need to show the oft-awkwardness of what is happening.
The dragon Age scenes were...mostly awkward though. Its much harder to do sex/love scenes well/right in games than on film, but when its right, its awesome. Thats my 2?
