If you have no internet on vacation, I highly recommend an RPG or something heavily story oriented.
-Fallout 1 & 2
-XCOM
-Dungeon Keeper 2
-Worms Armageddon
-Planescape torment (Awesomeness)
-Sanitarium (More awesomeness. Don't torrent unless you find one with full videos. 50% of the story is in the cut scenes. Some people didn't like it, but I thoroughly enjoyed it.)
-Freespace 2, with the mission creator for lasting epicness
-Emulators + ROMS?
-Dues Ex (Original) if you haven't yet.
-DWARF FORTRESSSSSSSSSSSSSSSSSSSS!!!!!!!!!!!!!!!!
-Half Life purely for the mods. The game itself was the cutting edge of bland.
-Morrowind + Mods and/or Oblivion + Mods
-Close Combat (First was good, 2nd was best, 3rd was good all around. Much action, thinking, and involvement in a short period of time. Good bang for your buck.)
-System Shock 2 (That is if you can even get it to work with XP/Vista. GET HEADPHONES FOR THIS.)
-Original UT or some similar UT/Counter-Strike freeware/opensource. Some rapid and light multiplayer arena shooter. Provided you have internet access.
-Alone in the Dark (THE original DOS one. Abandonia has it, I think.)
-One of the battlefield games (I believe 2 was the weakest. 1942 is still my favorite) + map maker. Custom epic battles.
-tyrian2000 for that quick arcade fix. Actually has a story.
-Most of the Total War series. Which was best differs from person to person.
For what is garbage I agree with Gota. Watch Yahtzee's review on Bioshock. Never knew how to sum up my feelings about Bioshock until I saw that. The developer's personally kicked me, a System Shock 2 fan, in the nuts with Bioshock. Masseffect was over hyped, and again Yahtzee nailed my complaints. I got to the third planet I had to rescue from robots, and then deja vu hit and I became bored. Half Life 2 was simply meh (and the friendly AI had lobotomies done on them). COD4 was alright (mainly because they finally made a game where guns acted somewhat like guns).
As a retrogamer, the Golden Years are past. 99% of everything now is crude and streamlined ripoffs mass produced from cookie cutters. The 1% is 99% Indies.
I dont like ... best get a good score from me.
Right behind you. Don't forget the multiplayer BS. I recall 4 player on N64 with bots. No bots now, and they're skirting more and more towards each player needs to buy a console and each player buy a copy and each player pay for online.
