A playable game mode that changes every day leading from the start of the all the way till now
Day 1/Betta version -would be bad graphics 1-2 payable maps and a select amount of tanks like : light,medium, heavy ECT:
Day 2 would be an update after starting game of wg choosing
It's only the updates that changed the game and showing what made it fun/popular back then
Maybe throw in some Easter eggs on previous events like have a mk1 destroyed on the battle field somewhere or the giant robot event that happened years ago have that in a background or something
This is to show what people have missed in the past especially newer players and being back good times
