Amplitude is a medium sized French company, published by SEGA just as CA, known for its Endless universe which is used as a setting in several games, mostly strategy games. As of now, the flagship Amplitude game is Endless Space 2
. It has some flaws, but it is overall a very solid and well supported game, so I encourage you folks to give it a chance.
Amplitude also has an older, fantasy strategy game, published four years ago: Endless Legend
, also interesting, if somewhat weirdly designed. Yesterday both games got an expansion. To this day, both games have been almost equally supported. It worked like this: Amplitude had decided to stop the DLC train for Endless Legend two expansions ago, with the Tempest DLC. People asked for more, so Amplitude listened to them (something they use to do a lot, to their credit) and outsourced two new DLC to NGD Studios.
Even if they had a new, and surely more profitable game out, they tried to be fair to their fantasy fanbase, and gave them four years of equal support. I won't say more, just compare that with Warhammer 2 and draw your own conclusions.
