Argo vs Company of Heroes 2
Argo
Argo is hardcore tactical MMOFPS that is, according its developers, a free total conversion of the popular Arma game franchise, specifically Arma 3. Although the franchise itself as not reached mainstream popularity like Counter-Strike, Battlefield, and Call of Duty, it has a niche and dedicated fanbase that you'll probably see a lot of while playing this game.Featuring a three competitive game modes and one 10-vs-AI cooperative mode, the game is set in the Mediterranean island of Malden that houses a range of combat zones perfectly designed to fit each mode. The game even has a built-in 3D scenario editor that allows you to create your own missions and other content for Argo players to enjoy!
If you love military-themed shooters, Argo is a pretty solid game to play. After all, you'll get to experience a bit of the famous "Arma gameplay" for free.
Company of Heroes 2
Company of Heroes 2 is the exciting follow-up for the original Company of Heroes game. Set in World War 2, this game is rather multiplayer-focused but it does provide players with an intense single-player campaign which also double as a way for you to be familiarized with the gameplay before heading into multiplayer.The game does have a lot of "standalone" DLCs that adds either a new single player campaign to the game or a new multiplayer army for well... the multiplayer gameplay which you'll have to buy if you aim to get a "complete" version of the game. This kind of make the multiplayer aspect of the game rather pay-to-win since players without the new multiplayer standalone, which usually features a new army that's slighter stronger, will probably be on a disadvantage.
All in all, Company of Heroes 2 is still a great game from a great franchise, but it seems like the developers/publishers may have lost some favor with its player base mainly because of the slew of "standalones" that players have to shell more money for in addition to the "base game".
