I would say my top ten is prolly close to 50 games.
But a few would have to include.
Meridian 59(first ever mmorpg, built on a doom engine years ago, open world pvp, lots of guild vs guild combat, and me Genocide, Pestilance, and Dark Figure pking every chance I got) Felt like a rpg(lite), but played lightening fast like a FPS. Best EVER Online RPG, yes more fun then wow, by far.
Civilization(serries, too hard to nail down what version, tho Civ iv is my fav).
Phantasy Star Online. Played this on Dreamcast, Gamecude, Xbox, PC, played the "Universe" version on xb360 and PS2, and played the "portable" ones on PSP. Think Diablo in space with JP flavor. I have dedicated thousands of hours of my life to this franchise. I will buy the PSO reboot coming next year day one.
Gaurdian Hereos. Sega Saturn, 2D sidescrolling multiplane, 4 player co-op beat em up. Set in a fantasy setting, you can play and level up several classes from wizzard, warrior, healer, ninja. Crazy fun game, think Castle Crasher, but in place of the lame "humour" is more fun.
Dragon Force, another Sega Saturn JP style game. And people say I don't like JP, lol. This game was the best strategy game on a console, maybe still is. I saw my youngest play it again a few months ago, the game has still got it and aged well. You pick a kingdom, rasie your castle levels, build your armies, search for treassure, and officers to recruit. Then you invade other castles(there are over 40 of em I think), the battles are fought in real time, with as much as 100 troops against 100 troops. Your general vs theres. Picks your formations and watch the battle unfold. Use your generals skills and talents to influeance the battle. Fantastic game.
Grandia II, Sega Dreamcast(later tweaked and rereleased on PS2). My favo all time JRPG. It was beautiful. I mean really better then a lot of todays games - no lie. The DC could do 2D like no ones bizz. Great Voice Acting, fantastic story, and the leveling up system was amazing. You leveled up books and unlocked spells in them. You could equip and combine books/spells. Lots of options. There has never been a FF game that has even come close to the depth or pacing of Grandia II.
Ms. Pacman. I know it was a sequel, but I liked it alot more then Pacman.
Super Mario Bros 3. I would say you could include the whole franchise, but imo, the 3D ones have fallen short of the fun factor and boarderline on frustrating. I think SMB3 was the best, tho SMW is great, as well as the new super mario bros wii.
Diablo. My boys and I still lan Diablo II and we enjoy it each and every time.
Just a few of the ones that pop into my head.
Its like music, too many great ones that are far abouve the rest. It becomes hard to say what the best of all time is. Plus you have to consider the day and age the game was made/released. Pacman or Tetris might seem flat for some newer gamers, but to me they are near perfect examples of a game should be. Like PSO, its all of the action of RPG w/o the long winded over done story lines that bring so many games down, but to some that might also feel flat. I like extras and goodies in my games, but after a while you understand that many games forgore the core experience, the satifying bits, to give you extras. Kind of like cake, nice, but you need a meal first. Cake alone will not sustain you.
Someday maybe I will sit down and list my fav games, based on merrits and do a whole write up, but for now I am spending too much time enjoying and playing them. Infact i have steam paused(Titan Quest) to visit here. I was looking to keep the spam under control in the forums.
Well back to chasing down another Telkine!
