Mad Games Tycoon (UP)

For this achievement you'll need a Production Room. I waited a while and saved up until I could afford several of the largest production machines, but you could do this with just one of the cheaper ones.

You'll also need to have made at least 2 games. This can be made by you or developed for someone else (contract work). You must also have re-released them as a Budget Game. You can see my solution for that achievement here.

Once you have re-released at least 2 games as Budgets, you can release a Games Bundle. Click on the Production Room bubble and select Remarketing > Game Bundle. Select at least 2 games from the list, then a timeframe and packaging costs.

Unlike Budget Games, Bundles do not use old stock, so you'll need to produce some more stock.

Hope this helps!
