PC suggestions here.

The Space Quest series from Sierra. May be available on GOG. Also, Outpost, also from Sierra. Outpost is an unparalleled RTS game more in the vein of M.U.L.E. than Command and Conquer. This may also be available on GOG.

Oh hell, why not also play Myst, 7th Guest, and Phantasmagoria while you're at it.

Just click on my games list via my sig. Then look at the two columns for VC.

Shining Force 1 & 2 for Genesis. They are available through Steam or the Genesis mega pack for Xbox 360. They are fucking amazing! Probably my favorite SRPG's of all time.

My favorite game on the genesis was Shining Force, it was amazing, I lost count of how many times I beat it.  Shining Force 2 was good, but I like the first one the most.

Get SEGA Mega Drive Ultimate Collection for the PS3 and 360.
It's called Sonic's Ultimate Genesis Collection in North America.

You will have the best Mega Drive rpgs:

Shining Force
Shining Force II
Shining in the Darkness
Phantasy Star 2, 3 and 4
and
The Story of Thor/Beyond Oasis, which is a great game.

You will also have the Streets of Rage series, and the Golden Axe series.
And more great games, all on one disc.
It's almost too good to be true.

Of course it's even cooler to play these games on a real Mega Drive, like I can , but that will cost you
hundreds of dollars.

There are many more great games on the Mega Drive not included in this package of course.

There are 4 new traditional rpgs released for the Mega Drive/Genesis the last couple years:


Beggar Prince, in 2006
Legend of Wukong, in 2008
Pier Solar, in 2010, this game is also planned to come to the Dreamcast, X360 and Wii U
Star Odyssey, in 2011, English version of Blue Almanac (1991)


Get these games if you are a hardcore rpg gamer.
