Good time to buy stock in Square-Enix?

SE's development as been pretty lackluster for the last several years. not everyone liked FFX. a lot of people did not like FFXII or FFXIII

Final Fantasy X was wildly popular. It's one of the most popular Final Fantasy games. Maybe you should step outside of the forums once in a while and meet with real people. It sold 6.6 million units. It was so popular, it became the first Final Fantasy game to have a direct sequel. FFXI was a huge success as well, becoming one of the best known and most-subscribed to MMORPGs of all time. FFXII was also a huge success. It won Game of the Year awards, sold over 2mil copies in Japan, was the 4th best-selling PS2 game of 2006, and sold over 5.2 million copies as of March 2007. It also has an empire of merchandise and spin-offs. FFXIII was the fastest selling title in the entire FF series and sold 6.7 million copies as of last month. FFXIII-2 has sold 2.5 million copies as of last month.

and FFXIV flopped as well

If by "as well" you mean being the only one to flop, then sure.

of course i'm not sure how these games did in Japan

All of them except FFXIV did well in both Japan and the international market.

EDIT: For comparison, the original God of War (which came out in 2005) has sold 4.6 million copies as of June 2012. Halo 3 has sold 8.1 million copies as of June 2008 (don't know if/when they'll update that). So FFX-XIII-2 are no mice in a world of gaming giants.
