It is well worth it: https://store.steampowered.com/bundle/8559/Company_of_Heroes_2_Master_Collection/ But there's a lot of content and depending on what you are looking for, not all of it is needed. Allow me to break it down:#1) The only thing you need to get started is the base game, Company of Heroes 2. a singleplayer linear campaign from the Russian perspective. gives you acces to TWO factions for multiplayer: Wehrmacht (Eastern Front Germans) or Soviets. #2) If you want to expand your singleplayer experience, get Ardennes Assault; a singleplayer non-linear campaign with unit customization and from the US forces perspective. #3) If you want to expand your faction options in multiplayer, you can pick up any of these: US Forces Oberkommando West (Western Front Germans) British Forces #4) If you are hungry for more content after all that, there is also the "Theater of War" scenario packs (solo and co-op available): Case Blue Victory at Stalingrad Southern Fronts REMEMBER!: ALL of the above is included in the Master Collection bundle. #5) After all that, if you STILL want more... PvP and PvE mutiplayer has a ton of staying power: Over 50 different unique commanders to unlock with special abilities to help customize your play style. Over 100 upgrades known as "Bulletins" that offer small buffs to specific units. Over 100 different premium camo skins to customize your forces.
