I'd also recommend that your first and second personal games are original works, (so future employers can see that you can think for yourself) and games that are embarrasingly super-small and short. So much so that you'd almost feel that they are embarrasingly small.
Why? Because what you need for yourself and others to see is experience putting stuff together from start to finish, and actually completing something and releasing it. That way (for the future) you and other people who need to hire you will see that you actually "git 'er done" instead of giving up half-way through. :)
This is much more easily accomplished through super-tiny games, and you get to see what type of games you like, etc.
Keep on Creating!
