Ticket to Ride
(the only match where I played both, and boy is this hard. When in doubt, pick the classic, but let's face facts, one of these two I haven't played for decades, for reasons of long playing time, rare player count, and awkward n-way-draw endings.)
Power Grid
(never played Blood Bowl, but American football does not really click with me, and Power Grid is one of my favourites.)
Tales of the Arabian Nights
(never played Goa, and Tales can be a PITA if you are not in the mood for it. Still, you got to honour the yuthor's work on that.)
Magic: The Gathering
(never played Pandemic, but a bit reserved towards cooperative games. Space Alert didn't score with my family.)
Tichu
(never played Tzol'kin,heard good things, but when in doubt, pick the classic)
Terra Mystica
(never played Niagara, but TM is the shit.)
Dixit
(never played Hanabi, but Dixit hits our table very often)
Agricola
(never played it, but rlying on everyone else's opinion.)
