I started playing those 1 hour games at work and really like a game that can be played quickly that have some depth, but not "break out the spreadsheet" depth..
Colleretto is my choice for a light quick playing games with some strategy but not too deep. I like Big Points too.
Tzolk'in is really kinda fun (Spinning gears), then some people figured out a "Dominant strategy" for winning consistantly. Making me realize these games are a delicate balance and no matter how much you test..
