I've played with that a couple of times | but always end up reverting to x-plane. But flightgear has some | nice features and also a nice community. It just doesn't look and | feel anywhere near as good as x-plane (which is a tall order | because it is very good). | | Anyway, I checked out some footage on Youtube. Visually, it has | nothing on even Flightgear; which I'm pretty sure probably has | some combat mods. Or even any version of that the last few | decades or so, actually. It actually reminded me of some dos | games I used to play in the early nineties. E.g. Jetfighter II | (released 1990) was pretty awesome back in the day. It looks like | that but with higher resolution. But e.g. the ground is a | featureless green blob; just like in Jetfighter II, and clouds | are white polygons hanging in the sky, etc. And Jetfighter II had | a HUD that was about as feature rich as the one in this game. Of | course it was way more pixelated than this. But they even managed | a cockpit panel :-). I wouldn't call it photo realistic but it | didn't look half bad for the time. There are probably | better/later game that this thing is shooting for. But I just | never really got into combat flight simulation. | | I guess they are trying to recreate some of that experience. Not | that it matters; but I guess the gameplay is more important than | the looks for this. Actually looks like it could be a lot of fun. | | BTW. I have nothing against MS Flightsimulator. The latest | version looks great. But I just don't have any windows computers | anymore at this point. Combat is not really something either of | the other flightsims I mentioned are made for or even good at. | app4soft wrote: | > _Nothing against closed source though._ | | To be clear, _YSFlight_ is partially open-source software. | | Here is official repo[0] of its GUI toolkit (OpenGL-based) and | various miscellaneous apps based on it. | | _PolygonCrest_ (aka `ysgebl`), an official 3D editor for addon | making for YSFlight, based on the same toolkit as YSFlight, is | fully free & opensource. | | [0] https://github.com/captainys/public | | [1] https://github.com/captainys/public/tree/master/src/ysgebl | | [2] https://forum.ysfhq.com/viewtopic.php?t=6374 | galcerte wrote: | Yeah, but it is a shame that the rest is closed source.
