Yes having online would have been great, but honestly for scrabble the cpu with its access to every word in the dictionary is as tough an opponent as you can get anyway, so no big loss. I also like the anagram mini game that helps build your vocab. The only complaint i have so far is that the dictionary used is a bit iffy imo. Im no scrabble veteran, but it seems kinda arbitrary on what words it accepts, ie. "vocab" and "te" (musical note) are allowed but "econ" and "june" are not. Still worth a go if youre looking for a true "brain" game.
Im getting no freezes/problems on the r4.
