Oh, sorry ... I misinterpreted the question.
I highly doubt you'll be able to do 4-player local co-op. That just seem like too much for one system to handle (not to mention it'll be impossible to see anything)!
I'd more than settle for 2-player local co-op with another 2 online.
I'd be content with the latter, but if it could be done on the N64, then why the hell can't it be done now?
I don't game online. Straight up, I don't. That might change as I get older, but for right now, I play multiplayer with my friends in the same room. Oftentimes we go back to Goldeneye or Perfect Dark if we want a four-player first person shooter experience. I think Timesplitters, Halo, and Metroid Prime 2 are the only games I can remember recently with four player split-screen. (Oh yea, and Red Steel. Big deal...)
Screen size shouldn't be an issue unless it is HD (which the Wii is not). I remember playing Goldeneye on a 13 inch TV and I was happy. I don't see any issue with playing any split-screen multiplayer game and it pisses me off a lot that there is a lack of quality in four player split-screen first person shooters.
I don't get why so many people care about online when there's something like five games per system that get any kind of consistent play.
I was thinking about getting We Love Golf a while back, but one of the secret characters is only available through online play. How many people play that now?
I bought Condemned 2 back when it was on sale at Best Buy. There are achievements tied to the online multiplayer that had NO ONE playing it.
It's just stupid to me. Give me my damn split-screen gameplay back.
Thank god for Mario Kart...
I'm in a very similar camp to you, Nron. I didn't do a whole lot of online gaming until I joined this site with Wi-Fi nights and all that. Even still, I have a good deal of gamer friends but most don't own Wiis. So I bring mine to gatherings and we play on the same system. So when it came out that Conduit would not have either LAN or splitscreen play it was very disheartening.
I have very little pity for devs who claim it's too hard to make splitscreen games run. That is the standard I believe and any online components are secondary. They should have gotten splitscreen up and running a long time before even bothering with online.
I'm still holding out hope that Grinder or even Conduit will be revealed to have LAN options. They keep using really odd phrases to describe online play. Words like network. I've not seen people refer to online the way they have in a while and it makes me wonder if they got the option cleared by Nintendo for either Conduit or Grinder or both but are saving it as an E3 surprise. We can only hope.
