The one major improvement is that you're having to buy just the full game instead of 2 variants. The chances are you already have the original full game, and using that to teach a reduced set makes sense if you don't wanna (or can't) buy the smaller set because it will stop being fun in a year once the kid learns the main game. There is also the fact that some games won't even have reduced sets (Guillotine for eg), or will have it but it will be impossibly hard to get where I live. I can easily get a copy of TTR in India, but finding a copy of TTR:1st Journey is much tougher.
