Hi :)
I've got the university pack, I've tried it out only the once on one of my sims though and I have to admit I also had the harder experience to myself which I didn't understand as my sim had the genius trait also and had a great childhood.... maybe the subject matters?? Or DNA from parents experience etc I'm not to sure or maybe every experience is different to make this more realistic in gameplay, what ever the reason Id say I like it!! It gives you more than one expectation of the game and the expansion pack and a different view and gameplay each time, but that's just me as I like to constantly try something new with my sims. I've played sims since the first one came out so around 16 years (most of my childhood)
If I'm going to send my sims to university again, I know that its literally study, eat, rest, go to class. Also I've noticed you can do the degree with up to 5 classes all at once, now I'm that advanced of a player and I tried that and damnnn was that hard haha! So I decided second time round to 2 classes at a time. I know that this takes longer and sims lifespan goes before sometimes this is possible to finish but I know I can buy the potion of youth to extend the stage of the lifespan, or I'm pretty sure in the options menu you can extend the sims full lifespan, I guess its each to their own and what each simmer prefers to do, I guess some like the challenge of not extending their sims lifespans and taking on the full 5 classes! :) :)
I'm not sure what else to add in here but I do adore this expansion pack so I could talk about this one forever! <3 <3
