My biggest worry about Half-Life 3

They could do even worse, like putting microtransaction in the game! D:

HL# Milestones:

step 1: HL3 made on Source gold
step 2: Migrate to Source 2 and add new textures and models

if step 2 isn't completed before Source 2 then go to to step 3 else skip step 3
step 3: start migrating to Source 2

step 4: release ;)

That it would be an other average corridor shooter...

ha ha! HL3 thats funny
never heard this sequence of words before (and never will)
