Im missing a lot of charm that w2 and first starcraft games had, and i did not see any open engine recreations, nor clones that lived to this day. With warcraft 3 i only ever finished half of the game, by the time sc2 came out, i was already too old to even bother trying.
Oh sorry it seemed offensive or negative in any way, I just wanted to clarify that “seems like” i s a vast understatement. Dune 2 predates all of them, and became a template for mechanics and layouts. We’ve gone a long way since, but dune was the first of the models that we build RTS games as today
