What a coincidence! I was just thinking about firing this up today!
Here is my three-step plan:
1) Have everyone study programming, until your character has achieved skill 4.
2) Use your character as team leader to design an engine for the Apple II (whatever genre, I don't care), with all the advanced features you can select at skill 4 and maxed out everything. Assign the other employees to help design the engine as their latest training classes finish (no more training at this point), paying extra for early completion if any of them only recently started their latest training.
3) As soon as your engine is finished, pimp that shit. For the first engine sale, maximize the time and profit, and assign everyone to support. Then, pull one employee off each week to sell the engine to somebody else, until you've got one employee per supported game.
And that is how you play GameBiz II. Oh, I guess you might want to make a game, but I've never actually played along with the board of executives. Also, buy back your stock. Buying back stock is a terrible, terrible grind, but you need to repurchase it.
With those employees, you certainly won't be making any games anytime soon. I'd suggest ignoring the board and instead just pimp out your engine until you can afford to buy offices. Then hire people talented in design and graphics.
You might consider building an office immediately. It's just that good.
Random thought: I know nothing about game design, but I always imagine that Toady One represents Programming while Threetoe represents Design. Patron deities and all that.
EDIT: Ok, after playing for a little bit, the game reminded me why it's impossible to achieve the goals: This game is bugged. Not a lot of bugs, just one major one: If your publisher doesn't make enough games to meet demand, YOU GET NOTHING. Which means that with your starting game prestige, you'll never be able to find a big enough publisher for the type of game necessary to achieve the third goal (top 100 rated game), at least not in the time frame given.
Fortunately, engine support increases game prestige, which is why spamming engine support is not only profitable, but also prepares you to sell games later.
