twesterm's my friend now.

All-time favorite? Xenogears
Last-gen favorite? Skies of Arcadia : Legends

FFX was my most favorite.

FFVII and Earthbound are tied to me as the best evar.

Griffin = fail as usual
Mine is obviously Earthbound
Though my list is thus
1. Earthbound
2. Chrono Trigger
3. Final Fantasy 4
4. Final Fantasy 6
5. Final Fantasy 7

Sad isn't it? the day of the good RPG died with FF7 on PS1 which I would argue that FF7 itself killed it, it became so popular that all other RPGs wanted to be it, even the FF games after wanted to capture that popularity, but bottom line FF7 barely makes my top 5 as I have half a mind to put Paper Mario TTYD or Super Mario RPG in its place

KOTOR. Im a big fan of Star Wars, and despite the fact that it was set in a completely different time from the movies, it had a Star Wars vibe like no other.

Honourable mention - Chrono Trigger.

Final Fantasy VIII. Still my fav, even though unpopular. Call me a hopeless romantic.

@Sky Render

Tales of the Abyss is derivitive of Tales of Symphonia, which was by the same team, had the same gameplay, and came out years earlier. Both great games though.

Of course, the best RPG of all time is Fallout 2, but it's not MY favorite, FFVIII is, so pwnd.

Oh, here's a great one:

Secret of Mana

Mass Effect

Oh I know about the relation between Symphonia and Abyss. I own both and have played both. I had far more fun, however, playinjg Abyss. Largely because of the free movement system, which was one of the big lures of SO2 (previous holder of TotA's title on my list, and the reason why it's my most played RPG).
