VB5时代曾经有个外国公司开发了一款VB+DirectX的三维游戏。至今国内到www.vbgamediy.com还能见到一些人在用vb开发3d游戏，但很少有公司或者工作室以商业目的去用vb开发了。
至于vb为主开发的大型软件有很多，尤其vb6时代很多财务、ERP、OA、教育、会议系统等大型应用软件都是vb开发的。快速应用型开发一直是VB的强项。自从dotNet平台出现，vb.net更是跨入高性能、更强大的平台，不过由于出现了新兴语言C#，国内很多人追新追C类型的语法。事实上在国外VB做大型项目的企业是非常多的，国内搞很多东西都有较为偏激的潮流。事实上没有不好的语言，只有不好的程序员，就像画家不是因为笔的差别而画不出好画一样。
