lets be real, no game would ever release that much content for free.
Really now, they don't? Let me give you a prime example.
This is all what Starcraft 2 has and its all shipped with the game:
Starcraft 2 (both expansions)
- Over 50+ campaign missions
- 3 races to play as with dozens of different ways to play the game as each race
- Hundreds of achievements to unlock by doing various things. They can go from Winning games to doing something crazy.
- Unlockable Player Avatars, Custom Decals for your forces, Dance/Cheer Animations for units, and unit skins.
- Extension Mods allow you to change the way you play the game or even create your own. They can go from having Zombies randomly spawn around the map and attack the players, have infinite resources, have all 3 races available from the start of a game, or spawn whatever you want/change unit abilities.
- Map Editor that lets you create just about ANY type of gamemode you can think of. I'm still blown away as to what people can make.
- Ranked and Unranked Matchmaking with up to 8 players.
- Intense Ranking System with Bronze, Silver, Gold, Diamond, Master, and Grandmaster Leagues. Good luck trying to get into Grandmaster.
- Watch Replays from your games, download Replays from other people, and you can watch them with others. These Replays also save to your computer so you can upload them to YouTube if you want.
- The game has this thing called "Swarm Levels" which allow you to unlock various Avatars and custom decals for your armies to show off. You gain exp for building units, killing units/buildings, buying upgrades, and winning. Each race has a maximum Swarm Level of 35.
- You don't even have to play the core game. You can just spend your whole time in the Arcade and play ALL the games that the community comes up with.
Oh, and you can't do any of this in any sports game:
