... here's mine: 1. DECREASED MOBILITY & STAMINA, serious health effects of having lost blood (due to injury), such as shorter sprinting distances/stamina, decreased running speed, further risks of going unconscious, being able to run at full speed infinitely is just stupid, add stamina to the game that works sort of like in fighting games, the more strain you put on it the longer it takes to recover. 2. MORE INFECTIONS and INJURIES - I want to see infections being a more real part of the game, different kinds of infections, such as bugs from drinking uncleaned water (water bottles) that have health effects (passing out, fever, throwing up, etc.), limb infections from bites (remember we are immune against the Z-virus), broken arm (leading to effects such as being unable to use a two handed rifle), also items that help prevent this, such as water purification tablets, splints, antibiotics, disinfection pads (that you can rub over a wound after getting bit), etc. 3. CLIP MERGING - I want more options for ammo, such as finding individual rounds, and being able to combine two half-full mags into a full mag, also separate rounds and mags, finding a box of bullets but owning no mag should prevent you from using the rifle properly (basically, on some weapons you can only have one round in the chamber. 4. WEAPON RELIABILITY - I want some of the M16's to have a higher rate of jam whilst using full auto, I want MG barrel replacement (where applicable), I also want a chance/risk of weapon reliability failure if you do not maintain your weapon, and items to maintain the weapons (oil, pieces of cloth, etc.). 5. SIMPLE BUILDING - I want to be able to manufacture a simple shelter, shelters will protect against the weather and can be used to help against diseases and such, a shelter built next to a lit fireplace will allow you to sleep. For the "fun"-factor, the sleep cycle will be something like 5 minutes but will put you at full stamina, and have a small chance of curing your disease.
