Nah, I never cared much for cheats. How about a new way to upgrade your character? Just picking them in a upgrade screen was so out of place. Do it Skyrim style. =P The more you use your pistol, the better you get at shooting. The more you run, the longer your sprint bar will get. The more you take damage, the more you can take. Perhaps a perk screen as well when you get enough XP points where you can choose perks like:
- Get less damage from fire, falling, cars, explosions.
- Lose notoriety faster from one of the gangs/cops.
- Get more money from killing pimps/gangs/robbing.
- etc.
Upgrade your weapons more in Friendly Fire, allowing them to deal more damage and hold more bullets and perhaps chance the way they look by choosing colours and designs like the Saints Row 2 pistol. And more different kinds of weapons and of course the choise to have dual pistols or single, that you can choose at all times in your safehouse/friendly fire.
Be able to customise your safehouses' interiors. Different walls, floors, furniture. See cutscenes when you start the first level of an activity and more activities. Day/night cycle and base some activities on the time of day like street racing at night or fightclubs in a dark alley. More activity rewards like unique clothing sets, cars, weapons, skills, fighting styles, moving styles.
More activities like Crowd Control, Demolition Derby, Fight Club, Fuzz,
Septic Avenger, Piracy, and perhaps some new ones or just more varieties of the ones they have now and had in SR 2. Instead of just 2, put in 4 of every activity in a different setting. Fuzz will be mostly the same, but why not 2 rounds of pleasing your camera man, and 2 rounds of a special agency asking for the protagonists help with 6 missions? You get to wear a tux and do James Bond like missions.
Crowd Control with 2 rounds of protecting some celeb, and 2 rounds of beeing a bouncer at a club, throwing out missfits. They did it with Trailblazer in SR: TT. You had the Tron-bike version and the normal version. Escort you also had a normal version and a tiger version.
Here is a far fetched idea that could be cool. Bring stealth into the game for example with Hitman missions. Dress up like one of the ( whoever the enemy gangs will be in IV ) and just walk inside without them attacking you unless they see you for to long. Find your target, follow him/her to a secluded location and kill him, then just walk out. Or just stealth in general. Hide from your enemy so they will start to search for you so you have time to regenerage your health, then pick them off one by one without them noticing. You already had the silenced gun in SR: TT, why not give it purpose? And perhaps a wall-hugging move for better cover. Most of the third person shooters have that nowadays, so why not bring it to the Saints? Would look cool if an army of cops were all positioned behind copcars, shooting at you while you cover behind your car, seeing your character grin because he/she is enjoying him/herself.
More clothing options. Be able to build up your costume from undies up. Choose undies, top, shirt, coat, pants, socks, shoes and misc items, glasses, hats, masks, and be able to wear them all at once so you can make your own sets. And more character costumisations like your walking style, fighting style, hight, idle style ( like how your character will dance if you are idle longer then 10 seconds in a dance club or how your char plays with one of your weapons of cellphone when idle longer then 10 seconds outside ). And a barber shop so you can change your hairstyle for a few dollars instead of paying 500 in Imaged as Designed.
And another idea I had that could be fun is a good/bad meter. And not talking about how you get more bad when you drive over civilians as that is kinda hard not to do in Saints Row, but the outcome of several missions where there is a good ending, or a bad ending. They already had those a bit in Saints row 3, but other then one building beeing destroyed and the statue beeing blown up, you don't really see any changes. Let them have more impact and have more endings where you can choose. With the good choises, the city gets cleaner and more peacefull and the civilians will become fans again. With the bad choises, the city gets dirtyer, there is more fighting on the street, more bums, more drinking, more drug use and civilians hate you. It won't have any impact on the story itself, but will add when you are just going around in the city to look for collectibles.
Strongholds need to return! Fight for control in your city/cities. Why would beating a Genki show give you a hood? Would the enemy gang be like: "woah, he beated the Genki show. We better back off and let the Saints own this hood."? No, of course not. Unless they are really chicken... Bring back the strongholds. They were hard and fun to do. You really had to fight for your hood. And even if you owned it, the enemy could still try and retake the hood so you had to go back to defeat the enemy commanders. And only after you own a hood, you are able to buy property in that hood. Made more sense that way. Kept you from buying and expanding from the beginning where you made millions within a hour of gametime.
Those are some of the ideas I had. In general, it's more of Saints Row 2 mixed with Saints Row 3 to make a great Saints Row IV.
