1: Controls, I hate controllers . Even for fighting games I prefer my good old qwerty keyboard . I simply can not play well with just my thumbs, I need to use all my fingers for buttons, 1 or 2 buttons per fingers, not a thumb that controls 4 of em... That's because I'm used to it since 3 years old though and not used at all to a console... Mouse is essential for FPS and RTS imo...
2: Mods, let's be honest, GTA SA for example is many many times better on pc due to M TA and SA: MP... Plus graphics mods, content mods, etcetc... Various games are a completely better ( read as better) game after mods...
3: Upgradability& Graphics: I hate being stuck to the sameish graphics for 5 or more years, need a gfx upgrade more often. Also I like higher than 30 framerates many genres of games, and I like being able to add AA, etc when games lack it...
4: Having 1 system for all: Downloading, Films, Series, Music, games, msn, internet etc... ( A console would not download torrents, would not house 3TB of data, would be a pain to use msn/internet on, afaik it doesn't support more than 1 monitor/screen... A practical pc imo has 2 or more monitors...), you say why it is better for gaming, because it takes less time to fire up a game from steam when you feel like it when browsing or whatever than to turn on a console, find a game, input disc, and play... I have to do something physical rather than 2 clicks on my mouse...
5: I can't play around with my console as much, eg. mess with drivers, hardware to make my system better, I love tweaking& playing around with bios, drivers, overclocking, etc... And a bit of childish ''my pc is better than yours, if not I'll make it better'' syndrome .
6: Emulators, a pc is also a PS2, PSX, a N64 or any older Nintendo, etc... Game catalog is simply mahoosive...
I really couldn't put it better myself. I will add my own notes to some points.
1. for all games bar fighting games (in which i use a stick) and driving games (i use a G25) the mouse/keyboard is king. No matter what console kiddies tell me.
2. Yes! Espically with games like Oblivion, which are far from rubbish and a lot of them are amazing.
3. Play ALL games at 1920x1200 with 4AA at Max detail. I already have a monster PC, why not use it anyway?
4,5 and 6 i just agree with
Also there are a ton of amazing games that will never be avaliable on the console. RTS's mostly and i love them.
Saything all that i still heart my PS3
