The PS3 has
- The largest and most active fighting game community (based on my experience with BlazBlue)
- All the critically acclaimed JRPGs (fact) and FF13 Versus is a PS3-exclusive
- Superior versions of the most popular JRPGs (fact)
PS3:
FF13 (1080p CGI and 720p Gameplay, NO framerate problems, 1 BluRay)
SO4 (Japanese voice option, improved targeting in combat, 1 BluRay)
360:
FF13 (576p CGI and Gameplay, framerate problems in Chapter 11, 3 DVDs)
SO4 (No dual language option, horrible english voice actors, frequent disc swapping when backtracking)
There's only one obvious choice if you are big on JRPGs. The PS3 complete dominance over Japan's HD market means that every single blockbuster JRPG is practically guaranteed to appear on the PS3 from now on. Not to mention the collection of exclusive niche JRPGs that shows up every now and then. (in fact, one was announced in the forums yesterday)
Since you consider yourself an 'old' gamer, you will probably be able to appreciate the masterpiece that is Demon's Souls.
There's more innovation and fresh ideas in that game than an entire decade worth of JRPGs. If you are willing to try something new that forces you to think, don't EVER miss out on this game.Read some of the users' reviews in metacritic http://www.metacritic.com/games/platforms/ps3/demonssouls
Fighting games tend to sell much better on the PS3.
Tekken(PS3) : 1.47 mil Tekken(360) : 0.74 mil
It is clear where most of the fighting fans are at. And keep in mind that unlike the 360, playing online with the PS3 is completely FREE. There's nothing stopping you from playing Tekken online every once in a while.
At the end of the day, if your passion lies with JRPGs and Fighting games, choose the PS3. You won't go wrong with that decision.
