Did I do all these estimates? Absolutely not. All of these estimates were influenced (as in I took into account someone's estimate when I was estimating) and even made by
@strivingforperfection @JGUIDO @Adrok @Clod @SaintGirth @RokiD @Lance Bass @Saure and many more.
Of course there's a lot more this already took like 40 minutes to make and I don't feel like nor care about doing more. This is a good starting point though
