The guys who made Torque 2D has announced going down so when using this engine is fine - don't expect any more updates or bugfixed at least not before some company will buy the game engine source and develop it further (which no one can promise you)
Multimedia Fusion 2 when being very advanced and developed, with solid user-base and support is very dated and it has "ways of doing things"(mechanics?) needlessly mixed in sometimes very user-unfriendly fashion.
Construct is a open source and freeware game engine being developed by just a few people - that's why don't expect any rapid development. It et better and better but the progress is very slow and some bugs are sometimes left unfixed for years (now, go on people troll me as much as you want but that's my opinion). Still thought, its quite simple to learn and you can make almost any game with Construct.
Game Maker has some very bothersome limitations, confusing mechanics and some hardcoded obstacles which you can't change without breaking the ToS. Still, it has huge user-base, lots of support quite quite wide possibilities
[quote:3iermld1]Does Construct have any memory leak issues
none that I can think of.
[quote:3iermld1]The loading times of different levels are similar over time? (the same level loads in about the same time each time?)
That's totally up to you - the GameDev. Layouts(maps?) in Construct can be huge, it deals quite well with big numbers of objects or particles.
In its current state, does Construct have any known game breaking bugs?
You have to describe what exactly you believe to be game-breaking as it has MANY game-breaking issues for ME which most of other users label as "trivial".
[quote:3iermld1]5. How fast bugs are solved? I have to ask this, as some game engines are updated quite fast, and others are updated once a year or even less. We cannot wait for an entire year for a minor bug fix.
then with all due respect - I wouldn't chose Construct. As much sympathy as I have for Construct developers and understanding for their little team member work capabilities, facts are facts - the development of Construct is quite slow and some annoying issues,broken features or bugs might wait months to be fixed and patched. Months or more.
[quote:3iermld1]6. In its current state, do you think that Construct is capable to create a commercial ready game? (multiple rooms, multiple levels, lots of sprites, sound, music, effects, multiple resolutions, many hours of game without crashes or glitches)?
Commercial? No. Indie? Yes. The limits of the engine are mostly linked with end-user(the players) PC machine. For example, I can throw about 5000 x 64/64 pixels sprite objects into the layout and don't notice any slowdown. But the guy next door will have a delightful slide-show. The games made with Construct will be as good and as bug-free as you will program them.
Look around, most of people here made or are in progress of making a game. Check their games and see yourself what Construct is capable of
[quote:3iermld1]As I said before, I personally think that Construct is the most intuitive and easy to use, but the other guys are really worried about stability.
I would be more worried about another thing. Construct at current state does not enables one to share his work. Technically. You can't "merge" cap files. Forget about 3 programmers working on different game aspect as all their work will be forced to be again imported into one cap file. In case of Construct there can be mostly just one programmer/coder. So yea the same guy who programmed the GUI, will also have to program the animation, system, mechanics, preferences, events and in general - put all the assets together. No work sharing.
Construct is FAR from being perfect. Its damn far from what I dream of. But the fact is - its probably the best 2D game authoring tool you can possibly find.
"In the land of the blinds, the cyclop is the king" I suppose.
[I can only imagine how much bashing ill receive for spreading the heresy that Construct is not perfect ]
all in one - if you don't have a good experienced programmer, go with Construct, its easily the best authoring program as for today. But if you do - now, that's another story
