have to agree with the emulators, although im not totally adverse to the RTS, I'm very much old skool and prefer the Turn based stuff of old.
GBA emulator with the ROM Gripper gets you access to classics such as Advance Wars 1 & 2, Final Fantasy Tactics Advance, Golden Sun, Fire Emblem, Tactics Ogre, Zelda, Mario Kart and *dum dum DUM!!!* ...Yu-Gi-Oh and classic Pokemon games. and best of all...al free

Great time killers, and most last for AGES.
games from the Andy Market? for sheer replayability, 'Robo Defence'. TBH, its a lil old now but im my eyes still a very balanced Tower Defence game.
Angry birds, well...nuff said really lol
Really enjoyed 'Game Dev Story', good business and creative sim, animation reminds me of theme hospital for some reason, but anyhoos, was a bizath attampting to get the game of the YEAR!
Tank Hero...fun as it reminds me of Tanks! from the Wii Play game
Slice It, awesome challenge, really simple but hard as heck when you dont try use hints lol
Everlands HD, turn based hex game, a lil like chess, nearly as in depth with starting combinations and unique character abilities, but with cute animals instead
moron test, is a good one to play in between friends when your hammered
x construct & spaghetti marshmallos, fun construct physics games
has anyone played Spectral Souls on their DHD? any good in comparison to other Tactics games from the PS2/GBA era?
