This. I think about it like alot, thinking if a zombie outbreak happened where would be safest place and stuff in my house lol.
Also 28 days later wasn't zombies it was more like a rabies kinda thing to living people and they died eventually from hunger I believe and got weaker as time went on and they hadn't fed. Where as Resident Evil zombies were dumb as shit, moved slow and didn't have any need for food to survive they are just driven by the 'need to feed' but the need bit is more like a want 'cos they are to stupid to know anything more than a basic thing like that lol.
I wreckon it would be 'cool' like you said at 1st and as long as only criminals/trash are being infected but hey if 28days later can teach us anything it is that 1 infected person can lead to the entire world being infected

There was this little game I played I think it was called 'infection' it is kind of like habbo hotel gfx and you have a chemical bomb to infect like 3 ppl in a city of like 300 and there are people with guns to stop the infection and your goal is to infect everyone in the city, pretty fun game

Lol
i think ur talking about infeconator world dominator, my buddy tells me theres a new one
