Personally, at this point in time, all I really want to play is DS'.
However, being level 143 and on NG+, every now and then I die again….and again….and again….and again….and need a game or two to turn to vent some frustration / kill some time before returning to DS' and getting through the part that was the frustrating me.
For me, those games are:
1 - Super Smash Brothers Brawl, Wii - amazing game, tons of fun, endless replay value, try and master all the characters, play it with your friends! I personally play as Marth because he is a fast, raging melee powerhouse with a counter (!!!!) (not unlike my DS' character!) and he slaughters quickly. Also, I can have my Wii and my PS3 on simultaneously as they are both hooked up to our 47 inch basement TV (dvd player, AV1, Wii, AV2, and PS3 HDM1) so it is two presses of a remote button to switch from DS' to SSBB.
2 - Star Ocean 4: The Last Hope - excellent game, tons of crap to unlock, and leveling up is not horribly tedious. TONS of achievements, excellent graphics, however, our 360 is ALLLLLLLLLL the way upstairs whereas our Wii / PS3 are way in the basement so I do not play this as much as I should. Still, even though I am only through about 1/3rd of the game, I am at level 53 (avaerage). Yes, I am an over-leveler.
3 - Fallout 3. This game is freakin' AMAZING. Call me a loser, call me what you will, but I have literally sunk about 400 hours into this game, with three different characters, and still love it. Forget the main plot line, just wander around finding every single skill book, item, location, etc, killing shit at will, on man, such an awesome game! I played the CRAP out of Fallouts 1, 2 and Tactics and Fallout 3 is DEFINITELY a worthy addition to the franchise, even though I (stupidly!) bought it for PS3 and as such can't get any achievements or get any of the expansions.
4 - Guitar Hero 1 - 5 / Rock Band 1 - 2 - these games rule on hard / extreme, and get even better when there are other people / instruments thrown into the mix! Countless hours of me and my friends lives have been wasted (wasted? I like to think not…) on these excellent titles, although Guitar Heroes 1 through 3 for the PS2 were BY FAR the most hardcore and challenging!
List your current games of choice, folks!
