Some random events could also spice the game up:
-Watch the news ticker for any gossip on new console release dates (affects when you decide to make game sequels and etc)
-Contact corporations to find out their console specifications (and sign contracts not to release details, try to prevent info leaks whether deliberate or accidental)
-Try to upgrade office equipment to protect from data loss (upgrading storage mediums, cloud backups/off-site storage) and keep up with next-gen console and PC demands
-Try to make games based on popular brand names and stories (get contracts from companies with famous cartoon characters and etc)
-If a contract to use characters and etc from other companies is lost, you need to replace much of your game with a new character or decide to scrap the project entirely
-As your office size grows and decades pass, maybe create a small "trophy room" which shows your past games in glass case displays
-Maybe a crowd-funding parody/minigame too?
There's even the areas of community building, advertising, lawyer work to produce EULA and Terms and Conditions that don't upset the modding community, deciding whether to release modding tools, what platforms to release on (target audience studies).
