I believe that this is the single most important opinion Volition and Deep Silver need to pay attention to when it comes to the future of Saints Row, and it's DLC. I too enjoyed SRTT and SR 4, HOWEVER, I gave great consideration to the fact that they where struggling with THQ. I felt the games where good, but fell short of their potential. I think that Saints Row 5 is by far the most important game Volition or Deep Silver will release in the next few years. If Saints Row 4 is the most content they can fit into a game for $60, what exactly are they going to do now that we've had an official generation jump. If the past two games and their DLC fell short of our expectations, imagine what our expectations are going to be in two years. Last generation Developers offset the expense and time spent on graphics/physics by shrinking the gaming worlds. The better the graphics, the smaller the world. This had nothing to do with the specs of consoles. This was a matter of budget, and time. Now graphics are expected to get better, and worlds bigger......gonna need a bigger boat....I'll stop there.....it's on the cusp of the topic anyways...In conclusion, I beleive SR 4's DLC was a way for DP and Volition to give us a silver lining on the future of Saints Row. A chance to blame all of the shenanigans on THQ and move forward......however, the game and it's DLC practices haven't seemed to really change much with or without THQ.
I completely agree with you, and it's exactly how I feel. In relation to graphics, having a nice blend between cartoony and realism, with smooth animations, is how I feel they should work forward. Allowing for absurdity within the customization, whilst also allowing realistic character designs for those who desire it. Saints Row 4 can be quite pretty as times, and I hope in the future modders will refine animations and textures in a way that makes them age well and look nice. It doesn't need to be a powerhouse of a game, but good art direction can overcome graphical fallout.
Another important aspect, is that the world needs to feel intelligent and alive. I'm not sure how much is possible for Volition, but having AI feel intelligent (not necessarily realistic) is important. Enemies need more than 1 to 3 models, and have to fight cleverly, and become a thrill to combat. Pedestrians need models that don't repeat very often (and when they do, design it in such a way that you barely notice), have smart interactions with the world. Peds should be on the rooftops, caring for gardens, calling people on phones, playing pool, trying various sports, laughing with each-other, going on a cross country trek in their Toads, arguing, driving intelligently, being offensive, being polite, all depending on what they're near and what they look like.
Police should have interactions other than immediately shooting you, and should only do that if assaulted or considered necessary.
"Sir! Get down from that mailbox! Now!"
"Hey! Watch your language! The middle finger is not necessary!"
Mam you're going to need to get out of your vehicle, you have caused a crash."
"Sir are you okay? You've been in an accident!"
They could also have more interactions with other officers, and have regular everyday interactions with the player and other civilians, polite and hostile.
Along with having the ability to customize everything (your homies possibly), you should be able to visit areas outside of missions and do activities within them. The best example I have is having the ability to go above the clouds like in those SR3 missions, harassing planes, and if they have a enemies inside them, allow for mid air combat as you plummet, instead of having it on rails for only two missions.
Obviously these are all just ideas, but Volition needs to be forward thinking about these things if they wish to stay relevant. If dlc is good, people will trust the company more and its future endeavors, and so far, I am quite disappointed still, especially by ETD. Better post launch support, and good additions, quality of life improvements, and optimizations to the core game, will help consumer goodwill on the track to whatever next project they're working on (presumably open world and customizable). I want to pay for more valuable products and keep supporting the team!
